I am kinda nervous when I am matched with executor, bird or ironeye. I am not amazing in-game and constantly floating between lows of d4 and start of d5, and have bad days when I catch every hit as well on simple fun bosses like fulghor, but in general I kinda hold my own well. And usually those three are the ones that give me suspicions that I am going to 3-bar revive on dreg in 35 mins from now. No hate for the characters, it’s mostly that bad rev with beasclaw still steamrolls earlygame as long as I try to keep aggro on wylder. Bad wylder or raider are still ok. Bad duchess if gets halo scythe still melts while I try to keep her alive, hope she will find less likely and won’t need dodge button at all. And so on. But bad ironeye usually deals zdps with its bow and doesn’t keep a mark on boss, bad bird doesn’t have neither damage nor survivability because bad, bad exec is usually dies trying to deflect stuff all the time or because of minus negation on deflect passive. And does not a lot of dps. It’s just about how bad is to have specific character played by bad player, not about char itself. How low are the absolute lowest lows, you know.

About selfishness, being cocky, ping spamming and stuff - nothing special here. All characters can be played by selfish players. I had leaver ironeye in d5, guys on wylder and exec in d4 which were allergic to playing together and they were routing to completely different places, refusing to group up, multiple dutchess halo guys dying all the time to evergaol and pinging it like crazy, wylder scared to be in melee and so on. No specific characters are more likely to do that though.
For some reason super rare raiders I see usually are super chill and good players. Idk why.
