I'm at the point where I am unable to solo missions and even side quests without dying a very large quantity of times, which isn't fun. I'm overleveled yet enemies still kill me [b][u]a lot[/u][/b] faster than I can kill them. I get the game is designed for co-op but I really don't like playing with other people. Even if I wanted to (which I do now cuz I can't progress solo without losing all my money to deaths), none of my friends play the game and randoms rarely matchmake with me even though I set matchmaking to public. Oh well. It was fun while it lasted. At least it took me longer to quit this game than the last new game I tried; Borderlands 2 lasted me like 30 hours while R6 Siege lasted me like 3. It's a good game, but I just don't think I can play it anymore.
If you get the right loadouts, you should be able to solo all the way through UVHM.
