Why not be able to change classes mid-life...why do you have to wait until you die. How about, if you go back into your spawn area safe haven you have the option to change classes on the spot. It's not like it would really change the impact of the game that much, it would just be more Pro-Friendly if the match starts to swing a certain way and it would be more strategic to change classes while in the humble abode of your own spawn safety point.
