trust me, you don't want to remove exp from FL,
i'm experienced in many PvP games, and many large scale PvP games, not that i enjoy them.
i still prefer traditional PvP matches, which are obviously more enjoyable

the problem with big scale PvP games is that, it will never be fixed.
all of these big scale pvp games have this problem.
you think there are a lot of people, but people who actually try hard is like 1 in 30.
if you remove EXP, 3/4 of the player base would be gone in an instant

also due to the nature of this kind of game mode, it's impossible to balance and it's just ball versus ball versus ball simply due to the number of players and it's far less personal skill intensive, that just heavily favors one strate that is everybody stack together and spam AoE buff/damage, which is basically only one role and only favors a certain type of class, unless you make every class the same there' no way to balance.
