Enemies Weirdly Too Difficult

hello there,

I play campain mode on my ps4 pro on medium difficulty but when I reached the level where I need to kill Belialh the Enemies Weirdly become Too Difficult to kill. I mean that i can spend 20 mins to kill one single enemy and they are a lot of them . The game is no more fun and doesn’t make any sense to play anymore . Is there something I can do to repair this ?

In think you can get sorted ! What class are you playing ? Secondly what is your build your for that character ? Lets start there to see if we can get tougher to kick some Denon A.s.s.
