Difficulty is way to high

I am done for now, cant even finish act2.
you nerf the shit out of this game(like -50% damage life etc) during the campaign and leveling or you will lose all the casual like me.
stuck after 15 hr means: BYE and play another game

That Act 3 Viper girl boss is a pain in the behind, worst design I have ever seen and I'm stuck on her. Her attacks come right after another and it's hard as a merc with the reload mechanic. I've had a fair few times that when you dodge an attack another is followed up behind it and it hits you. It's too much and it's the 1st time i had to Alt-F4 the game out of pure frustration.

Other bosses i worked out after a few tries but the Viper boss is on a whole another level of poorly thought out game design.

I've noticed different bosses really punish some classes, and i think GGG really need to rethink how some of their bosses work. We all cannot be mages spamming spark.

Difficulty overall isn't too bad, but some bosses (Act 2 main boss and the Viper Act 3 boss with the guards around her) really need a better look at them. Especially when gear for resistances have been few and far between.

i spent upwards of an hour on some bosses and absolutely loved it,

I would change flasks to have the gain x charges every second as a hidden mod,

Every skill availble in the early game should be scaled to be good enough for the encounters.
