Regardless of map or faction, colonizing cap (akkan, progenitor, or jarrasul) is best 1st choice 99% of the time...about the only exception to this is if you are on some map where the enemy HW is 1 jump away (then marza, Halcyon, and vulkoras would be better choices)...you play online in competitive games, you find that having a colonizing cap is essential to expanding fast enough (eco and frontliner) or relocating when you lose your HW (suicide spot)...additionally, some of the custom maps are an absolute bitch unless you have a colonizing cap...if you go into a custom map blind, it's best to assume you won't be able to expand very well without having a colonizing cap....
Those three ships also have extremely important abilities:
- Ion bolt on the akkan is your cap killer and ability disrupter ability, and armistice (lvl 6) is your lifesaver...of all 6 TEC ultimates, it is definitely the most useful...
- The progenitor has malice, the most important ability to couple with the Eradica's Chastic burst, and it also has shield regeneration, which is crucial to keeping your guardians alive (which are absolutely essential to Advent strategy now)...it's lvl 6 ability also is probably the best out of all of them (with cleansing brilliance a close 2nd)...
- The jarrasul has gravity warhead which is fantastic in cleaning up retreating fleets....nano disassemblers also is great for dealing with early game caps, SBs, and Titans...it's lvl 6 is probably the 2nd best out of all of them, with the Kortul's lvl 6 as arguably the best (I'd include marauder's lvl 6 but the opportunity cost of picking that ship is just too high)...
If you are eco player, you only need one cap to begin with....rush your titan, and once you have that, follow the below list as much as it resembles the frontline you will be assisting, taking into account what your frontliner has already gotten...
If you are TEC, I personally go with either with Marza, Corsev, or Kol as 2nd choice:
- If you are a frontliner and winning/pushing forward, having a Marza with raze planet can help you clean up planets quickly...this is particularly important if you are absolutely owning a player and need to wipe them out fast (either because your other frontliner isn't holding out or you're tag teaming a suicide spot)...
- If you are a frontliner and are holding the line/falling back, Corsev is the best pick...it is a fantastic tanking ship (get passive regen ability) and does great AoE damage...awesome ship defensively or if you are fighting over a contested planet with lots of frigates on both sides...
- If you are a frontliner and have to relocate or are eliminated (but somehow can get a 2nd cap out to safety), get a Kol...it's flak burst ability is immensely useful for dealing with bomber spam and you can still use your Kol to help protect your allies titans/SBs from bombers...this is probably the single greatest contribution you can give your allies with one capital ship other that just staying alive and having a planet (cause you did build that akkan 1st for colonizing, right?)..
TEC's 3rd choice (which should come after Titan):
- If you didn't get a Kol, get one to deal with bomber spam (this is crucial for protecting your titans, caps, and SBs)...Kol also is good at tanking...be careful with its AM usage, save it for flak burst...
- If you already have a Kol (or don't feel like you need one) get a dunov with EMP....this is your anti-titan ability as it keeps the enemy titan low on AM (and if they can't use their abilities, they aren't nearly as dangerous)...both magnetize and shield restore can be good picks as other ability....remember that magnetize is an ability interrupt (also kills SC), and I'd usually go with that...
If you are Advent, I personally go with either Halcyon, Discord, or 2nd progenitor as 2nd choice:
- If you are frontliner and winning/pushing forward, get a Halcyon for the extra bombers...this will help you clear out structures faster...make sure to get TK push, as that is your anti-bomber ability...
- If you are a frontliner and are holding the line/falling back, Discord is the best pick...fracture and scream are awesome AoE abilities that can help deal with large amounts of frigates....combo it with malice for greater effect...
- If you are a frontliner and have to relocate or are eliminated (but somehow can get a 2nd cap out to safety), get a Halcyon or 2nd progenitor...the TK push from the Halcyon can be a lifesaver for your allies if you follow one of their fleets and help protect their titan/SB from bombers...a 2nd progenitor (with malice) also can make the VR and TR titans immensely more powerful and is an excellent compliment to your allies' fleet...send one progenitor to each frontline and help them out....if you get both to lvl 6, you can resurrect virtually all your allies' caps should they lose them...
Advent's 3rd choice (which should come after Titan):
- You really want to have a progenitor with malice/shield regeneration, a discord with fracture/scream, and a halcyon with TK push/energy aura....so your 3rd pick is whatever you didn't pick 2nd...
If you are Vasari, I personally go with either Vulkoras or Kortul as 2nd choice:
- If you are frontliner and winning/pushing forward, get a vulkoras with siege platforms...just like the marza, this can help you quickly wipe out a pushover enemy or one you have on the ropes...
- If you are a fronliner and are holding the line/falling back/having to relocate, get a kortul...disruptive strikes is your anti-titan and anti-cap ability as it depletes them of AM and interrupts abilities...jam weapons also is great for protecting a fleet (whether it be yours or an allies') from bomber spam...and, it's lvl 6 ability is probably the best in the Vasari arsenal...
Vasari's 3rd choice (which should come after Titan):
- If you already got a Kortul, either Skirantra with repair cloud or the new Rankulus (whatever it's called)...
- If you don't have a kortul, get one...
This list is not perfect, and note that many things are very situational (what happens if you lose your 1st or 2nd cap???)...but, telling someone who is new and wants advice "well it depends" I know is frustrating...furthermore, personal taste does come into play...for example, I play AR and abuse wail like none other, so I'm not as concerned with having the discord for dealing with small frigates and instead go for TK push on the Halcyon...
