My only gripe with "high ground" damage is that it's still only 5% increases when everything else is 5% without relying on high ground. I think maybe it deserves 6 or 6.5% instead of 5%. My 0.02c.
Edit: As far as poly, I think each character should get level 1 just for the skills it supports. Being able to fly/hover while moving/skin graft are great skills. But repeated investments aren't necessary unless you're specifically building a shapeshifter
I agree. I felt that in the EA version it was nicely balanced between constant 5% bonuses or situational 10% bonuses. Now it seems they just went with the safe and boring route where everything gets the same bonuses.
