Stamina is the difference between smart players and stupid players. Smart players will use stamina with a bit of thought and use normal attacks sparingly. Stamina management is part of the battle tactics involved in the game. There's no need to dumb down the battle system more.

I have to laugh at the person saying they play Gladiator and spam basic attacks. Bad glad is bad. Any tank worth anything knows you should keep a reserve of at least half a stamina bar for emergency taunts. Seriously, burning your stamina bar at the start of a long battle is what bad players do.
