Need recommendations for a game

Hi recently i've been lost on what games to buy. I'm looking for a game to stick with for a very long time. I do not want to swap between alot of games so i just want 1 good game i can play for awhile.

Here are the game requirements:

- Looter

-Classes

-Really good endgame

​

ive tried games like POE, Warframe and ive enjoyed them both but ive become burnt out from those.
