Yeah, I've been mostly concerned with the smaller ship balance too so I'm curious to see if anything breaks apart in a battle with say, multiple cap ships. I have done
some playtesting with the capitals (a Behemoth can murder an Onslaught one on one with effort but can also die to a lone Wolf now, and a Caliph can take an Onslaught and a Conquest at once -- maybe not if they actually made a concerted effort to blow it up, but still -- but will shatter trying to fight a Paragon at equal FP, so those are pretty much working as intended), but not nearly enough in my mind.
I'm glad you think the design direction comes out that well in actual gameplay, too!
And for everyone else, I popped a quick guide to playing as the Kadur in the OP. Another one for playing against them will probably follow, for now I'm going to go to sleep though.
