As a person with a massive ego, I voted archer/cleric, since those were the 2 classes I rolled first. I think it’s more specific though.
I rolled an archer to oneshot people as a musketeer. I’d call that considerably egotistical. I like seeing that I have the most kills on my team after a TBL match, often even if my team loses. I’ll make a risky play knowing I’ll die if it’s a good trade (myself for their only healer or highest damage output, or multiple players).
I rolled a full support cleric because I like feeling important. Healing is generally tremendously easy and many are bad at it, so I like the ego boost when people think I’m God’s greatest gift to the earth for a clutch heal–when I did something so brainless.
And revenged sevenfold is about as scumbag as you can get.
