I can vouch for that also, it becomes "unfair" or and practically "unplayable" when your 3 out of 8 trying to get a flag in CTF and the other team is rushing you like zergs in SC ._.
I've seen better:
I've seen 5 of my opponents (red) out of 6 use Rockets to nuke the crap out of the Blue fort in Blood gulch, and still, until I've arrived, I started to spam grenades till they all died.
