Soul of the Forest posted an interesting question: what class do you refuse to play? Their bette noir is melee DPS, which is a very reasonable position to take. Staying alive is the key difference in playing and contributing well and being a dead weight, and melee DPS is always bottom of the heal priority whilst being in the most danger of death. I stopped raiding on my Rogue because I used to die too much too easily, but I’ll still play melee DPS as long as I’m wearing plate or have some good self heals.
I’m quite happy playing tanks of all descriptions, and love playing a Hunter obviously. I haven’t played a lot of healers in an MMO, but in Overwatch I love playing Mercy.
The class or role I just can’t bring myself to play is a caster. Something about using magic just doesn’t gel with me, and I can’t find a way to make it work. Despite casters being essentially a Hunter with lightning or flame instead of arrows and bullets, they don’t work for me.
The same fear of magic applies in tabletop RPGs like DnD, some of which is down to the overwhelming spell tables, but it’s also just not a class I can roleplay at all. It somehow seems too passive, or that it’s not me doing the work, it’s the magic.
So I guess my characters have to have some element of physicality to them, something with heft or guile or a pet and a bow. I’ll leave the weaving of magic to the experts.
