I just did 2 Hydron runs, leveling my crit build (Blood Rush, Body Count) Paracesis, (it was the only weapon I had for max affin) and Wolf lvl 70 spawned in both, back to back.
1: A team of Saryn(me), Chroma, and Equinox wailed on him for 10 minutes. We crowded him and managed to get him cornered against one of staircase railings that lead to upper level, Chroma's aura let us hang close and constantly wail on him...my combo counter was sitting at 3.5 x 650+ in the end, and he dropped a Molten Impact. 😧 Seriously! Even with this stupendous counter, I was hitting him for yellow and orange crits of 1200 if I was lucky, mostly it was hovering at constant yellow hits 800 to 900. My toxic lash was also active as much as possible.
2. Next hydron run... he spawns at wave 4. we have Saryn, Inaros, Vauban and Ember. With no Chroma I couldn't stay close. the others eventually running out of ammo, having to use Operators, Archguns (even these running out ammo eventually), essentially leading the fugitives on a wild goose chase, but it meant we could never concentrate all our fire/damage on Wolf. We were constantly getting downed, revived, downed, revived, ad nauseam. After 20+ minutes of this and only getting Wolf to about 6/8 health, I had to go to bed and aborted.
This Boss is... really, really, bad. Even with the recent cap on his level, its still a ridiculous poorly designed encounter. If you aren't lucky enough to have a good Chroma in your squad...
Just to put this into perspective:
A Lvl 70 Shadow Stalker has 564,550 EHP and 90% DR (the entire squad can concentrate on him, he doesn't have the super mobility of the wolf, and is alone)
Lvl 70 Wolf has 1,168,728 EHP and 86% DR + 3 Lvl 70 Invincible Fugitives that carry Incendiary Grenades that might as well be star plasma in a bottle, you get hit or just happen to step on the hot puddle - you're insta-dead.
DE, please go back to the drawing board on the Wolf. My suggestion that at least would make this better in the interim is to remove the Invincibility from the Fugitives.
