I dont spellweave on my Demo's because, like yourself, been playing for 6 years and have some experience to back that up. But, unlike yourself, I have had massive breaks in between, and my Demo's spray-and-pray (spray-on-prey? heheh) generic Waves builds sometimes far outmatch the random PUG raids I like to attend, quite often shattered (pissed, drunk whatever you wanna call it), for the sake of...
fun....
ZOMGS what a wasted slot!
Specifically the reason I dont SW is because I have DO have the experience, and quite often those pugs are there for a lot of people to cut their teeth (I admirte the patience of the couple of PUG raider guilds, Exceptional!) and it's far more effective to NOT be in SW. So, chaos ensues, and I'm left standing on my altar looking like a right fool, and incapable of producing anything meaningful to the raid as backup. Or run away /*cough* kite.
As Suctum said, your comment can be easily construed as elitest, (whether or not it is, well that's for intepretation I guess). We're not all in it to win it, sugartits.
Oh, and I quite often end up easily being top 5 on parsers. There's always a smart arse though who beats me, but I'm not really impressed =D Again, parsers are open to intepretation (AE builds in a mob pull fest? pffft)
