There needs to be a race-specific support cruiser that reduces healing from ability sources...
A battle-ball of fragile Gardas surviving a wail sounds particularly stupid. I was under the impression that wail dealt damage instantly? If so, how could the healing keep them alive? Or was it the damage mitigation from the Ankylon? There are a number of moving pieces at play, aren't there?
Figure out which one caused such a dramatic outcome in favor of the Loyalist player, and then bring it to the attention of the community.
I don't find flak to be the issue, however. We all know that flak is versatile and useful to build a fleet out of, no need to continue your debate of whether or not it's healthy for the game (I realize that I'm speaking to the deaf, but I figured I needed to actually say it
). If anything is overpowered, it's titans. They make fleet building against turtled defenses and large fleets so repetitive.
