How to solve oneshot mechanics and players "semi-immortality"

1. Tone down damage of enemies

2. Tone down regenerations and life leech massively.
Because this is why devs justify why enemies have to oneshot players. "Theres no other way to kill a player who nullify incoming damage 80% of times and the rest is just recovered in half a second"
Even the Doomguy can be killed and he is literally too angry to die.

3. Introduce defensive skills that comes with cooldown and tradeoffs

4. rework class identity just a tiny bit:
And here I mean Energy shield supposed to be the "meatshield" class. Seemingly have high amount of hitpoint, but the same time they get nearly unmitigated damage from enemies.

And we have two stupid mechanic that just scales off the chart.

Block should be reducing incoming damage not completely nullifying it. You have Guard mechanic in the game.

And evasion should be corresponding with recoup. Something similar of bloodbournes rally mechanic.
In poe mechanics evaded attacks are recouped.

Both block and evasion could get critical chance and critical escalation with a key node to improve their numbers.

I don't think everyone should get max resistance everywhere. I personally think only the templar should be the only class that could max out every defenses. Wonder what the templar/guardian will be in this game
