Eh, to be honest I didn't really try. I had less than a month to go for wrath; so I just did Daileys on my 70s. (I did alot of the haloween crap too, religiously farmed HH, lol, messed around on some old quest chains that i skipped). I did try Mgt a like once, but had issues with vex. (so, the answer is probably yes. tho i think thats supposed to be one of the harder instances. and I was in leveling-gear, lol) I then decided to make a hunter team for fun; and got really into them by the time wrath came out. tried to shift back into playing my shammies but couldn't get into it, so shammies are sitll parked at 70, basically serving as a massive guild fund for my hunters to play around with( Engineering x5 is expensive!). Its working out; the first time to 70 i did like no instances; mostly just did quests. My hunters are smelling the roses so to speak, and doing every instance; but almost no quests. Eventually i'll go back to the pally + shammies; but for now I'm having fun in content I completely skipped the first time around.
