You did great.... but

[rrra]

It's probably just the shock of experiencing increased difficulty in nightmare and hell combined with lowered drop rates. The endgame geared characters will undoubtedly be stronk but the road to get there looks daunting especially for a solo player. My vengeance pally has good damage but is so squishy it's just not practical to try and farm with vengeance. I need to respec into blessed hammer just to see if I can then contribute in a cow run whilest standing behind a wall of necro summons I'm sure we will figure it out.

This. I'm not used to having a 22k damage aoe spell (Warcry) that still takes a while to kill hell cows. I can imagine its worse for other characters that don't have a stun baked in. And I suspect playing solo just got a whole lot harder with this patch. Although I can't make a judgement given that we aren't even one day in yet.

if anything palis are in a worse spot than summon necros. imagine doing 7k zeal 75% chance to block with decent gear and still not being able to kill nm cows without dying a crap ton of times.

Zeal vs cows means you will be block-locked the entire time. Thats not gonna go well vs large groups of monsters until you can one or two shot them.
