Easiest 80 instance for rep grind.

Which of the 80 instances are the easiest/fastest/most rep ect?

Also

If you had an all melee setup (My Prot/Ret(Holy) Pally with my friends Enh.Shaman/UH.DK)... which of the 80 instances would be too hard to deal with?

Is your team capable of doing any heroic content? The rep grind on non-heroic may be unbearable unless you are prepared for a really long haul! If you do a heroic Gundrak and go to the south entrance, you can get a lot of easy pulls for 15 rep per kill. Like 2 trolls at a time, then if you turn into the shrine of Eck, you can do a bunch of 1-pulls on the guys in there. Also, Moorabi is pretty simple even on heroic. Give it a shot. If you have to do a non-heroic, you're looking at some bosses which are as tough as some of the easiest heroics. Try Halls of Lightning for a lot of easy pulls in the first room.

I just hit 78 today and my friend is not far behind... We've been doing normal instances on the way up with a moderate amount of success (4 manning mostly).

So right now I'm just in the planning stages... and I can't think of anywhere else I can ask a question like "Whats the easiest instance for an all melee team" than here.

Thanks for the input.
