Because you have to follow rules.
What happens when you break even one rule? Any and all agreements previously agreed upon, including informal non-ah related ones, are nullified instantly as we can see with Brent not wanting to tank for Foo.
Now I wont argue that co-ops dont work. Critical has never tried, how can you say caviar tastes yuck if you have never tried it.
But I mean really, how can you have fun with different posting strats if you have to follow set rules? All you can do are lame, tame, non-Critical-like stuffs. That dont sound like fun.
PS: had no idea u guys were on the same server.
