Frequency of the Downed State Mechanic.
most if not all one shot abilities are telegraphed ahead of time, either through animation or big nasty red circles…otherwise it’s from biting off more than you can chew. Being downed for the most part is user error. REviving isn’t a bad thing, you get achievements for X number of revives plus XP. Your other Cons as I suggested, wholly intentional as far as I’m concerned.
