There's a counter to everything in A/D gamemode. It doesn't favour only M4/M60 users like every other gamemode does. Every set has its weakness, you just need to be smart enough to figure em out. Every set has been decided by the community itself and we have concluded many times that it's completely fair. Any experienced A/D player would have no issues against RPG.
so you mean that DMing is not part of this gamemode? just *TACTICAL* ?
well how come I haven't seen anyone be so *TACTICAL* so far? what tactic, hide and wait for enemy to come at CP so you can torment him? this is pretty childish, players want action not random & cheap deaths
the difficulty itself comes from the gamemode, not the players
A/D depends on predicting the opponent's strategies and forming our own based on that. The gamemode you're calling childish is one of the oldest custom gamemode in this game and it's still one of the most played gamemode. Just check out any of the official match videos if you're keen on checking out the tactics. However, if such stuff annoys you then I'm sorry this gamemode might not be for you.
