If we're talking tabletop, I am the Dungeon Master / Game Master / Story Teller. I do not bend on this. After two and a half decades of hard work and trial by fire RPG storytelling, I no longer enjoy simply being a Player Character.
If it's a video game, on the other hand...
- Mage / Spellcaster: high risk / high reward and the best special effects budget.
- Warrior / Tanks: You get to try the biggest selection of the armory and weapon rack.
- "Monster Lord" classes: Necromancers, Warlocks, the nasty ones (fuck the druids and hunters)
Though to be honest, I've played so many fantasy RPGs, I tend to favor modern or scifi ones.
