Apparently they overlooked Covenant set bonuses, probably because noone wore them to test them out. Venthyr might actually be very good.
I never said using cooldowns properly was RNG. Just the adds and laser behavior is absolutely RNG. You can manipulate it all your want, but there’s no guarantee what you want to happen will happen every time. I don’t even need to use Frenzy because Defragmentation card does constant heal aggro, and I can see the mobs are yellow-threat building and still refusing to leave Velen alone despite that, with or without Frenzy.
I’ve also had Kruul randomly do his ranged shadowbolt thing on the Demon Hunter and instantly “kill” her for no reason whatsoever.
