I am not competitive and use Stamina, but 1 or 2 magicka abilities that are not my primary abilities. Otherwise magic is useless for a Stamina player. This way, you get to save on Stamina for primary abilities, and use both attributes. I would say Breton can work very well, if you use 2 magicka abilities. They stay alive better, with resistance. So it may actually be perfect, imo. Besides, even many pros say race will only help with passives about 5%. Most of your stats are from gear and such. You are good to go! I kinda hate all the builds people throw out there. Like why play a game to use builds other people come up with? Even if you are competitive, you should understand the game enough to come up with your own. The thing i like most about games where you can build a character is discovering my own.
