No DPS meter means no way of knowing what spec, or skill rotation is best. Sure, some people will argue "play how you like it". With such attitude, any kind of PVE content means it'll be impossible with bad specs, or trivial with good ones. I dont get why people are afraid to be outed by a DPS meter as slackers ... if you are a good player, then you should be able to find out good specs/rotations and a DPS meter would help you improve by a small margin. If you're an average player, and didnt find out a good spec/rotation, then a DPS meter will help you notice it, and point you towards a better way of playing. I'm an average player, and i need to improve.
