min requirements for healing reg 70 instances?Follow

That will be enough for most 70 instance (regular of course). MGT might be hard, but with a good group, it shouldn't be a problem tho.

Arcatraz might give you trouble (the meteor from the elementals at the end), but nothing that you can't fix. You should wait before heroics tho, once you have 1100-1200 healing bonus, you might feel comfortable to heal heroics. Personnaly, I waited until I was in the 1400 range. And I saw people from the board that went with sub-1000 healing and did fine. Everything depends on the group you have.

Is the mp5 your total in-combat regen or your +mp5?

Out of Combat almost definitely. Unless you socket for regen, you won't hit that much in combat until T6 level gear.

Most of the IoQD badge gear is T6ish level gear. Some of the pieces (like the legs, Grovewalker's Leggings) have a lot more regen than their BT/Hyjal counterparts(Kilt of Immortal Nature). If he only has 601 +Healing then I highly doubt he's wearing badge gear.

You should be fine, I was healing instances with about the +healing as a moonkin spec, so if you're a healer you should'nt have too many problems if your group does'nt totally fail...
