I too have problems with parties in ARPGs. It's just no fun when people are running everywhere killing everything before you can even see it on your screen. Not to mention competing for loot... all of it just makes me very stressed. I want to go at my own pace.
Been thinking about playing PoE again actually (especially now with crafting that's less... RNG: The Game), but the one build I have in mind that makes me want to play, requires a unique to function. And I don't like the idea of making a new character, levelling it up, then grinding for items just so I can do the same with a character the way I actually want to do it.
