Premades are fine...this is not a problem.
This is the predictable rhetorical monologue of a person who runs in half premades and plays only non-ranked warzones.
For most guilds they simply cannot muster 8 people on a regular basis to play in the sacred 'RANKED' warzone. They say things like "when we are all max geared" or "on this one day out of the week" but it never transpires. What they slowly get recognized as on our server are pugstomping guilds. Bullys need only apply.
