Suggestion / Question 2 the Community: "Atlas for full Shrine+Corruption+Exiles is too hard ?"

Header refers to the Suggestion and looks for more Opinions.

Here some emotional information:
By skilling all points for "Shrines" in the Atlas + all points to double-Corruption + all points to Rogue-Exiles, all in all i am always one-shoted by any "unknown" issue refering to some sort of red Ground-Area, any Grenades exploding, Projectiles from the far, teleporting Hard-hitting Mobs... more reasons. As we dont have a Logfile for Fights - i cant skill against those DPS altough i run easily T16's corrupted, irradiated and +3 at Boss-Atlas, almost one-shotting everything except the Boss.

How you feel about folks ?

My Suggestion is a severe nerv to those Mobtypes.

Greetings.
