I think it took me about 45-60 minutes a level. basically gather treasures, do your garrison stuff, and clear objectives and use your garrison experience potions

Cool, thanks guys. Any recommendations on classes?

I have an 80 mage and 80 pally so I can levels those or choose a new class for the free lvl 90 I'm given with the expansion

Highly considering a rogue

Usually only took me 30-45 minutes a lvl depending on class.

this is about what i get

Totally up to you! Personally out of those three rogue is my favourite but that'd be in bg's.

Was considering coming back but seems like game just getting worse and worse sadly

Brain dead*, which you seem to be.
