Realized early this week why i quit wow 3 years ago. It's literally impossible to raid and have a relationship with the other sex.
Just depends on what kind of guild you are in. I mean if you are raiding like 4+ nights a week then yeah. But I normally only raided 2-3 and only a week here and there would be 3 nights and I cleared everything in a decent time span.
It's only really ever hectic in a progression guild in the beginning of raiding tiers, once it is on farm its usually a 1 night clear. In tier 11 content after the progression was finished, we were clearing all 3 raids on Tuesday night and that was that.
