TEC:
1. Akkan (Upped Ion Bolt, it's my anti-mothership ability, great for fleeing caps too)
2. Kol (Need a rock in the fleet, LRMS are fragile)
3. Dreadnaught (Now I can split into two fleets, Akkan and Dreadnaught with some support goes one way, Kol and most of the fleet goes another, the Akkan and Dreadnaught can destory planets and colonize while the Kol and fleet keep the bulk of the enemy occupied)
4. Another Dreadnaught
5. Dunov (Gotta keep the caps alive)
6. Another Dunov
7. Maybe a Sova...it's rare I ever want a seventh...
Vasari
1. Space Egg (Evacuator, nanite bomb ability is the ultimate anti-cap ability)
2. Carrier (The Health cloud is a beaut and I like using it to support Vasari fighters/bombers, they're tough little bastards)
3. Battleship (need a bulwark in the fleet)
4. Seige Cap (need a seige weapon)
5. Maybe the marauder....with the 1.1 buff it'll finally be useful
3-5 are interchangable
Advent (Ahhh....the best ones)
1. Mothership (Need I say more?)
2. Halcyon/Seige
3. Seige/Halcyon (2 and 3 interchange, the seige can freeze enemy caps...very useful against vasari and advent, Halcyon obviously makes the fleet a lot stronger...and it's the anti-fighter cap...really depends on what my opponent made)
4. The Support one...never can remember it's name (Vertigo and Vengeance are beauts)
5. Battleship (I want animosity combined with Vengeance)
6. Another Mothership (Now I can split into two cap fleets, Mother, Halcyon, Seige in one and Mothership, Support, Battleship in another....that's if I need to, I like to keep them all together
7. Another Halcyon
8. Another Support
9+. The rest....if any, are battleships or motherships
I didn't quite follow what you asked for in the guidlines...but
#4. TEC it's the Dunov if you can get it to Level 6 (huge cuts in antimatter costs)
Advent it's the mothership. The thing has malice, shield regen, an ability to save experience on other caps, and it's got the best colonize ability in the game. Best cap bar none.
Vasari it's the Egg. This ship has colonize (worthless special ability), the nanite bomb, the gravity anti-jump warhead, and it's a seige engine by level 6. Probably #2 most valuable ship in the game.
