I admit when the game came out it was fine, everyone was level 30-something (Subway Beta) and i was already used to the **bleep** blindfire because of that same beta.
But when people started reaching level 50 and unlocking the FAL the game was unplayable IMO, all i saw was people running aroung killing me with either a KAL or a 4HK FAL. They'd use QB and Bargain all day.
I think what destroys this MP is what you can unlock, G-MAL and AK are there for default (when the game came out there was no Spyder M9 nor any M9 you could buy in the PS Store).
Hopefully U4 will be more like U2, where everyone has a chance, having loadouts in a game where a weapon(KAL, FAL, M9 RoF) and/or a mechanic(blindfire) is OP is so unfair.
In short yes i do remeber the good old days and wish they was still happening now.
But its a uncharted 3 players dreams/my memories.
