State of Endgame and Warrior

First off, I haven't played PoE1 at all. Yes, I'm new to the PoE side of ARPG. Yes, I have much to learn.
Yes, I understand, it's early access......

But the current state of endgame if awful. This mapping, rifting system needs to go.....tired of seeing it in ARPGs. There has to be a more innovative system out there that can put this tired trope into retirement while still being fun and rewarding.

Why it's awful:

Difficulty ramps up too much from campaign, even if just doing a level 1...
When I die to unavoidable one shot mechanics, I lose 15min - 20min of gameplay by way of xp death penalty. If you're going to punish me for dying, at least make the maps a bit more rewarding for completing successfully instead of just looking forward to more map keys to continue dying in.

On to the warrior:

Overall, I think the class is very fun to play, but has a seriously rough time starting out. I understand the thought behind the warrior being a slower paced combatant with wind up skills meant to do massive damage, but....it's too damn slow. Please speed up the warrior at least a little bit.

Anyhow, campaign was awesome. Boss fights are amazing, and completing that journey (as it is now) was simultaneously rewarding and punishing. Nothing worth playing after campaign imho.

Thank you all for your time..
