Endgame Penalties

Greetings.

I won't beat around the bush - please remove Endgame Penalties.
I'm fairly casual player and I see no reason in all these punishment mechanics. Unless you want to make the game anti fun. You intentionally ask the players to increase difficulty of the game to "progress" and then punish us, when we got burned.

I'm level 71, running T4 maps as of now and I've just lost my second corrupted Nexus in a row. My atlas tree is empty.

Who thought that dying 1 time in a Nexus map completely deny your ability to receive Atlas Points is a nice idea? Please, tell me. It locks player for a 30-60 min away from the next attempt.

First Nexus I had Sky Seer boss. And no, I didnt die to Tornado. It one tapped me with another attack. I had 1k+ hp and low res. Okay, I had bad build and gear, I admit. I may have been underprepared. I swapped gear and build. 51% (57% with Wind Dancer) chance to evade, 32% to deflect, 75% elem. res. 1k hp, 1.1k ES. Flamethrower boss on T4 map. I dodge all attacks except one and he 1 tap me.

Same for exp penalty. A single reason for their existence could be Omen of Amelioration but that's a bad excuse.

Lock players from Citadels, Towers and Deadly Bosses. Why?

Players who want challenge play HC.

Leaderboards? Gimme the option to be excluded from them just so I won't lose any exp.

I understand and support buffing/nerfing/reworking skills, build, items, crafting methods.

I dont bait you. One moment I thought about throwing some money to get more tabs so my time in game would be more comfy, then I fail the second Nexus and I dont wanna touch this game again. For what reason you keep punishing those who gives you the money?
