Sincerly I consider AVA one of the most FTP games.
Why?
Despite the amount you pay, you don't need to upgrade every living stuff out of your character.
I don't think there's anyone that plays with all 3 classes in that many variable situations.
I never paid anything for AVA, neither I will because I can't, but I am doing well at the game.

I used all my living stuff out in that round, but yet again, non-GCoin-bought weapons and crap.
And one more thing, why you complain about AVA taking money from you?
Did you look at other games?
At other games donors pay for crap no one can get in an "earning way".
Take a look at... Roblox, Maplestory, Battlefield Heroes.
So don't you complain about AVA not being a truly FTP game, it isn't, but most of the stuff you would normally can use GCoin in can be bought with normal money.
Only game close to that is All Points Bulletin, but then their stupid premium feature comes in and forget them.
And on a sincere note to some limits, I personally love AVA more than InfinityWare's crap.
