Being able to queue up on any class an change to your preferred class and still getting exp on the class you queued as is the only real draw of Frontlines.. ive gotten my Garo mount from it and will probably only touch it daily for Exp from the roulette. If they removed rewards from it Exp, tomes, or marks then I'd have no reason to even queue up for it. If they only removed it from the losing teams then I'd probably drop out from any match that was going bad for me, and let me say that I've had a TON of turn around matches while grinding for Garo. There's no reason for me to sit in a match that I know I'm going to lose and get nothing out of it.

The suggestion is like asking for a hidden parse in pve content where if you don't meet minimum damage or healing numbers you don't get any items or exp.. dose it sound nice.. sure.. but it would completely ruin the game and SE goal of making everything accessible for everyone..(even tho we all know they are going to far with that currently)
