Is witchhunter a class that can even play endgame?

All the endgame content I see is like sorc or monk or ranger...

Is the berserker a viable class late game? I'm currently level 64 and my second time fighting Mektul is pretty disheartening, trying LOTS of combos with a very high damage build, but it seems like there isn't a configuration for a nade focused build that works.

Interested in feedback.

Witch hunter is really strong with grenades build, not sure with the lightning build, there is also a bleed build kinda work decent

LOL I just found a unique that let me merc Mektal on cruel difficulty after HOUIRS of work getting my ass completely handed to me.

It's gloves that convert my elemental damage to 33/33/33 fire/lightning/cold.

Wow is that OP on this build.

Mono-fire/poison damage can be such a huge weakness and all I have to give up is extra evasion and armor on my gloves to do get around it.
