I used the Characters tag because this feedback is somewhat tied to Astarte, and that is the only category that is even close to being relevant since mechanics don't have their own tag.
It is insane to me that a mechanic that RNGs you to death was allowed to make it to a live service game.
I don't even know how many times I have gotten to phase 3 and gotten Astarte (Ember Trek Normal 42) to A LITERAL SLIVER of health just to get RNG'd to death by the LIGHTNING that deals damage to and stuns a random character on your team. This past run (shown in the picture attached) I WOULD have cleared BUT my Massiah (whose turn was just prior to my Viper's) had the RNG lightning proc on him.
This alone will murder your casual playerbase. I HIGHLY recommend removing it.
