Q and E class select, is there anyway to turn this off?

Picture this,  you're fighting a tank and you die but can get a quick spawn near by. You do it, instead of pulling an rpg like the last time you pressed 3, you get **bleep** defibs? Who in gods green earth thought, " yeah battlefield players wanna change their classes with hotkeys!" 3/4 of my deaths it feels like are because i keep spawning the wrong class. Its infuriating, I want this game to be good so **bleep** bad but at every turn it seems like you try implement the dumbest things. 
I am so over this. I have never been this annoyed with one of your games. I want to play engineer, let me stay with **bleep** engineer. 

There is no way to turn this off, there is no **bleep** need for this.
