Way, way, WAY less than 1% made legitimate attempts at 4H. Saw I'm not sure. The vast majority of guilds were forced into cannibalizing geared tanks from other servers. Hell, I think we recruited five xserver warriors during Naxx?
That was mainly because 4H required more tanks than usual. You could get through almost all of Naxx with 2 well geared tanks and 2 off gear tanks. Then suddenly at 4H you needed as many geared prot tanks as you could find.
