Getting to level 100 shouldn't be this boring.

I've got to level 99, and boy oh boy, the exp is soooooo slow now, and dying? no can do, never again, or i will lose 2h+ even with amelioration omen.

Why can't we do something like t20 maps that gives more exp? harder stuff but more exp?
I remember in poe 1 there was some way ppl were getting to 100 without it being ridiculous.

We are party farming endgame maps. If you want to have fun with some slow-grinding party action add me and we can have fun. This game sucks solo after level 90.
