This is the fourth time I've been on these boards and have seen someone use the word "casuals" as an ad hominem attack against a position in an effort to dismiss it. This is unproductive and reeks of condescension. It also furthers a false divide between players of this game as it attempts to divide the community into two groups: those who are allowed to speak about the game and those who keep their mouths shut. Please stop, for the sake of the community.
I'll 100% back you on this. I disagree with you on flotillas and activations, as you saw from my statement, but I hate it when people are dismissed as "casuals."
As for the ship cap, I agree Ardaedhel. A ship cap wouldn't do anything. I think the most reasonable action at this time, if there is any action to be taken, is the simple soft nerf suggested by the OP. Limiting the usage of the Demolisher title to not include Engine Tech movement does a lot to limit the flexibility and threat range of Demolisher. This, combined with the wild card of flotillas, should be enough of an adjustment for wave 3. If Demolisher is still king after that, then it's time for more drastic action.
God. Don't go to the X-Wing Forum, then....
