I'm flexible on the days of the week I can raid but I would highly prefer fri/sat/sun 8-12am.
That being said, I'm an older mannoroth player that enjoys fun and long walks on the beach, bodies falling in my wake.. I truely get pumped about progression and pride myself on being early to raids, always prepared and read up about the upcoming fights for that evening.
I've MT'd for most of my "WoW career" and find that there's nothing quite like it.. I do run a frost OS but as of yet it's not much to look at.
Currently I am grinding rep for my shoulders and a few other peices to boost me over the 470 mark. That being said I'm confident that this character can handle all of MV normal right now.
