I would really like to see a few new anti-bomber tools. Perhaps add 1 research topic to each race(shared by both factions) on this topic.
Perhaps something like:
TEC: Superior Blast-shielding(1 level): Grants capital ships an additional 1 armor per capital ship level against damage dealt by bombers(to a max of 10 extra armor for level 10 capital ships). Frigates gain a static extra 1 armor against damage dealt by bombers.
Advent: Telekinetic Overdrive(2 levels): Each time an advent fighter squadron deals a killing blow to an enemy ship(including a single member of another strikecraft squadron), that squadron gets +10/20% weapon damage, max speed, and acceleration for 2 seconds.
Vasari: Suppressive Fire(1 level): Enemy ships damaged by vasari fighters are distracted for 3 seconds. Distracted strikecraft have their accuracy reduced by 45% and distracted frigates have their accuracy reduced by 15%. Capitalships & titans are unaffected.
Wellt hose were just the first ideas that popped into my head. The point is I'd like to see each race get a new technology to help counter massive bomber spam. I figured a buff to bomber-killing speed was appropriate to advent(as telekinetic push already gives them great defense against bombers) and a defense booster would be appropriate for TEC(as they have no real defensive measures against bombers but have 2 cap ship abilities for killing strikecraft. Perhaps my choice wasn't ideal for Vasari(since they can already jam strikecraft weapons), but I liked the idea.
I suspect all three would be mid-late game Techs, perhaps something like 5-7 military lab requirement.
