These strategies keep people intent on knowing how to mass things and press a button to win. There really is no strategy behind them. Fleet wiping abilities are and always will be stupid in my eyes. Because they are not balanced. It makes games rule by who gets there titan first or who has the better choke point spawned by the randomly generated map builder. They really are not strategy, I know how to counter them, and countering them takes far more effort then actually using said abilities.
They stagnate the gameplay and limit far more strategies than actually create.
I'm with Sareth on this one. There are a lot of abilities that are useful almost universally. Meteor Storm, Debris Vortex, Flak Burst, Shield Restore, Flux Field, Finest Hour, Nano Remit, Explosive Shot, Snipe, Suppression Aura, Mass Disorientation, Telekinetic Push, Repulse, Amplify Energy Aura, Shield Regeneration, Chastic Burst, Detonate Antimatter, Missile Barrage, Ion Bolt, Phase Out Hull, Disruptive Strikes, Drain Planet, The Maw, BRB, etc. I could keep going very easily. These abilities aren't few and far between as you suggest. They are common parts of the game that all are very powerful.
To try to single out Bombers, Chastic Burst, shotgun, etc simply isn't correct. They are powerful, yes; very much so, but that doesn't change the fact that powerful abilities are common. BRB is the primary tactic used by the TEC Loyalists now that the Nova got capped. Chastic Burst deals less damage than shotgun and is only on this list because of Malice. which still caps its useful target count.
Beyond that, it's not really fair to say that the offensive ability of a super-offensive race's titan is too powerful because it's universally good in combat. Likewise, a super-defensive race's scorched earth weapon is universally useful, but that doesn't make it OP either. Numbers make things OP in almost all cases; concepts rarely do.
Bombers are powerful, yes, but you seem more intent to annihilate them via slamming them with the nerfbat so hard that no one will ever use it. Remember what happened to Malice? A mainstream ability that every Advent player used and loved got nerfed into the ground compared to it's previous levels of power. Only because of Chastic Burst is it worth the AM now.
Bombers don't need to be nerfed into the ground or removed. I'm sorry if you hate them, but doing either of those things is not the solution. Just give critical-mass bombers a counter. That's all that's required. You don't need to nerf them. Just counter them when in large numbers and the problem is resolved. They don't need to be wiped out of the code. I really think you're overreacting here...
