yeah same, didn't do LFR, but I did the normal 10man.
Healed it on my druid, which never did any FL bosses, and has 372 ilvl gear equiped, the basic VP things.
we went in, like " let's check it out" most were just 1 shot, others 2 shot, no real difficulty, no mana problem, no tank wipe, just TOO easy for a normal 10man imo.
it was an alt raid with people in 378 ilvl gear, so, not even outgearing the place, just the right equipment.
I knew LFR would be easy, or noone would use it, that was a given before the patch. But I hoped 10man would be somehow wroth it.
But like the 5man instances, if you don't have people standing in the aoe, you have nothing to heal in those. I was above 85% mana, even on bosses, without innervate. those dungeons give a TON a gear with quests and drops, I mean, it's free loot right from the start without any nerfs.
