I somewhat disagree with this for a couple reasons. I had 4 members come back to the game that hadnt played since early EARLY cata or late wrath. They were solid raiders. They stepped right into our core group without hesitation or complaints of the skill level desired. In fact, the ONLY reason we downed lei shen is because one of those people who hadnt tanked since that period came back and happened to be on for that one night. He stepped right in and didnt miss a beat. 493 ilvl guardian druid to be exact.....his home life causes him to miss raiding full time, so he is a sub in as needed.
