Confogl is the best. The only globally accepted competitive mod for l4d2. No one who is any good plays team versus. Confogl teams that 'rage' have probably found a proper match on the clan network. I'm glad you enjoy your friends games- but imagining you are good at this game is ridiculous and offensive.
What usually happens in team versus:
confogl player: hi guys
confogl player: confogl?
*no response*
confogl player: erm..guys
newbs: no gayfogl ****
confogl player: some verbal retaliation
Confogl just sucks all the fun out of the game. No T2 weapons, pills everywhere (quicker to use then medkits, so why have them?) and it doesn't fix the random spawned commons, which tbh is the biggest balance problem in a vs game, the horde amount can be different for both teams and the placing can also make it harder for one team then the other. I wouldn't begin to see how to fix that, but confogl doesn't attempt to address it.
I like some of the changes confogl has to offer, but as any team I've played confogl against rages when they start losing that as well. I see no point. Also they usually say "not playing finale" if they are winning or losing.
Also, on making it harder on survivors it makes it easier for the infected side. That's balancing? Next they'll stop infected players from using the right mouse button to swipe calling it a balance fix.
If you are a pr0 at a game you shouldn't need to change a game to make it suit your playing style. So confogl loses.
Insanity changes things for both teams to try to make the game less frustrating to play with players of varying skills. Higher skilled players should get further, lower skilled die quite quickly. (Also, I save Insanity for friends games only.)
If you "pr0s" think you really are good, why not play Realism VS mode more, you know, an actual official game mode, instead of moaning at other Team Versus players to play your modded game?
