1. + 11.: Shank E.R.A? that sounds super cool, i'm excited to see what it and the reworked assault kit does!
3.) yeah the Airena is awesome and I think it's my personal favorite of the mechs,
but I did realize in my excitement I completely forgot about valiant charge in the pankrati talent which does the same thing but once per scene instead and have at thee is once per round which also kind of stepping on everest core power territory, but judging by your response your already working to weed out that stuff
8.) Huh I didn't know that about british english I learned something new!
9.) hmm that might work although the gilgamesh exists and pretty much turns any limited system into unlimited systems at LL 6 you could have gilgamesh II tarantula III ghengis I which does make a cool image but might be a bit strong in comparison to other things at that level, which is why I suggested maybye lingering terrain and smoke shells (smoke shells as a passive) be combined into a core power instead and have the current core power reworked into a system. but maybye that has it's own balance issues.
12.)hmm that one is tough, I as just thinking about on how to make it interact with how many targets it hits but I couldn't find a way to make it balanced
edit: anyways thanks for making such cool stuff
