Funny for me it's quite the other way round:[...]Return Fire sounds like a reasonable idea. I play Infinity, so shooting back is a "Yes, please!" for me.
Not too sold on the idea of extra action points. Seems a game-breaker.
The scaffold sounds just plain fun.
- Autoreturning fire? No! too easy to abuse, you park a unit behind cover, shoot at your enemy who autoreturns but does hardly any damage because you are behind cover and he isn't?! wtf. I'm all for abilities like "taunt" and whatnot but making auto-return fire a normal thing doesn't sound like a good idea to me. Also there are stagger abilities and other stuff that will drain action points. So this is absolutely not needed.
- Extra action points with abilities: This was already a thing in Age of Wonders (spells like rejuvinate and quick dash, abilities like invigorate) and then there were tireless and sprint which you could count as extra actions too. AoW:SM also had double strike none of those broke the game and since I expect action points to play quite a big role in planetfall I hope extra actions will make it in! I'd also be fine if some units just had more action points than others by default, why not?
- On the scaffolding might already be in the game, I mean there already are exploding cars. I'm fine with that.
