I fought a human who didn't use repulse. Just got Illlums, Illums, and more Illums. It's not a bad idea in theory. Just get shear amounts of DPS to crush. He had 100 Illums and a progen/halcyon and like 8 guardians.
I played my first 50 games with advent without even building a guardian. only won 49 of them that way.
late game aside, im gonna talk about a few key points to keep in mind when your fighting an advent player, the late game will be decided by early and mid game, so thats what you should focus on. As a point of reference my points are gonna be confined to 5v5 scenarios (since thats where people usually have the most trouble with advent).
Firstly, anything other than massive illum spam/halcyon/guardians can be pretty effectively countered by TEC. And recently I've come to the realizations that an advent who wants to LF/scout a TEC is making a huge mistike, since TEC's only LF spam can bring it hard, faster, and stronger and paired with a marza youll knock the advents friggin lights out.
TEC vs Advent in the late game is quite possibly one of the hardest matches to win. First of all, your opponent will have guardians with repulse,which can push away any short-ranged combat units. Secondly, he's going to have telekinetic push that will disable and damage large groups of strike craft. These powerful abilities severely cut down on your options. You cannot lean heavily on flaks or heavies because they will get repulsed, and you cannot lean heavily on fighters or bombers because they will become victims of TK push. You basically have to rely on LRM's as the core of your fleet, which leaves you very vulnerable to being countered.
Darvin is right on the money as to WHY advent has such an advantageous matchup against TEC, but speaking from a high level of play....I feel it is incredibly foolish to build any LRMs early or midgame against an illuminator spam. 40 LRMs MIGHT beable to take 20 illums...factor in malice and shield restore and youll probably need more like 50 to take 20 illums. Provided the advent player is using them properly.
Secondly, YOU MUST HAVE THEM SCOUTED...I know that goes without saying but I dont think most people understand what i mean. SCOUTED does not mean you know where there HW is. SCOUTED means you have scouts queued to jump in and out of the advents strategic positions. You must know when they start producing illums and beable to react IMMEDIATELY. If you cannot start producing when they do then you can expect to be on the defensive for the rest of your empires existence. Also, hitting them fast and in sufficient number is the only way scouts work. A certain Amish-man will tell you scouts become useless once they have about 40 illums, and i think that is LUDICROUS. Onces they have around 20, your looking at needing about 60 scouts to fight effectively and with malice and sidebeams at higher numbers scouts get exponentially less effective. If you are gonna use a scout based strategy, I suggest a rush, and the sova would be your best bet as 4 bombers squads on a lvl 1 halcy would tear up a marza. the fighter squads would also be a great help for dropping constructors quick.
Dont get me wrong though, 20 scouts in a fleet of flak and LRMs are some extremely cost effective meat and firepower, just dont risk crippling yourself with a terrible fleet composition.
As Amish said, ARMOR UPGRADES. TEC has amazing early game defensive upgrades, and for good reason. I always prioritive those over offense because the tougher your ships are, the longer hoshis can heal them, which essentially means your ships get exponentially tougher from upgrades.
Against a fully blown halcy/illums spammer flak is absolutely your way to go, with a marza as well. just be sure to put on your dancing shoes cuz this strat requires very effective use cap micro and repair bays. use lose the marza and its game over. yes guardians will be a problem but the flak will negate bombers, and the goal is pressure the opponent constantly, you want to skirmish to get MB. repulse is hugely expensive, and for good reason, if someone rushes it prematurely they likely wont even have enough illums to render LFs completely useless. In this scenario SABOTAGE REACTOR (most underused ability in the game...right next to infailable jump drives....T--7 FTW ) is your best friend.
One last thing, DO NOT EXPECT TO HAVE AN ECONOMIC ADVANTAGE. I don't know who said that but...eeek. Even with an akkan advent cap colonize is about right on par. and if you have civ labs and tradeports then you dont have military labs or ships. and therefore expect to be on your back all game spamming scout (best case scenario) or joining a new game lobby (most likely scenario).
Ok hopefully I have a point or good advice in their somewhere, I have a hard time keeping on track when someone asks a question like "what should I do against advent". And I can speak in length about this matchup (900+ games too much free-time and an over-active brain will do that I suppose). But I have to cut myself off. Hope this helps.
apologize in advance if I hi-jacked your thread =P
