That's the only damn map I've played.
Most of the maps in TF2 are all symmetrical.
And yet you haven't considered all of the, oh, I don't know, payload maps?
Which are not symmetrical?
Or, what about all of the other custom maps TF2 has, which this game does not have or support?
Seriously, just stop trying to defend your game that is obviously not enjoyed here.
You aren't going to change anyone's opinion.
