This was always going to happen. I spent so long trying to explain that actually sins' DPS was ok despite the problems with DS animation and that as a 'whole package' (pvp and pve) they are leagues ahead of the other classes, but due to bias and ignorance from the server team it all fell on deaf ears. Now the gap has simply widened.
Also harry when you say a '7%' buff i think youre referring to the rough increase in attack speed? Which will translate to more than 7% in overall DPS.
Anyway, theres no point in turning this into another warrior vs sin debate as nothing will change now. But yes chasey, i wouldnt invest lots of time in your warrior as whilst sins have less HP they are the better class, just need to be on your toes a little more. Do what most others are doing and start lvling a sin, get to 48 for lvl 3 SS and youve basically completed mir :P
