I might be the only one, but I've found i've done less heroic 5 mans this time around, mainly because of the time it takes to do the dailies, then off to honour grind in pvp.
Thankfully (due to tailoring) I managed to skip pretty much all the 5 man heroics so I can go straight to LFR.
Don't think I've completed all of the 5 man heroics yet!
I've had Pandaren Ambassador since before 5.1. Burned out on dailies. Still run heroics and scenarios to hit valor cap and upgrade gear. Once I get the weapon capped out and finish the 6K legendary quest, I'll probably just shelve my main and diddle around a bit on my Paladin.
By the way, I did my first raid as a fresh 90 Holy Paladin. I had gotten tier legs from the Sha of Anger and then the boots from turning in the quest, but otherwise heroic and PvP gear. I was putting out better numbers than my Druid with ilevel 473 and a Sha-touched weapon with Int gem. The class is seriously broke as shit.
