What's the most braindead class spec that isn't going to give me carpel/cubital tunnel

The role doesn't matter.

I like to get to the meat of games as soon as I start. Don't really care for character complexity. I like to keep it simple.

For example, my most played game was Tekken 7 where I played Jack-7 who is a very simple character that played the game on a very fundamental level. No stances, not a lot of buttons, easy execution, easy combos and combo adjustments etc. I'm looking for the retail Wow version of this.

Edit: I kind of like the way enhancement shaman looks and fight but I've read many places it's a lot of work. This true?
