Open season on ALL Guilds!

No variance leads to less pvp. Most "fights" are stand offs between the two large guilds at the time to see who has more warm bodies and usually no pvp ensues due to the fact that most battles the winner can be predicted based upon numbers / levels alone. With variance and having to scramble a force to a mob, you're far more likely to see skirmishes over mobs. Having said this, I think it would need to be a small window.

On a personal note, I think non variance actually helps my guild. Variance would benefit the smaller guilds or crews.
