Finally got my 25toons up to the 372 level two weeks ago and tried the LFR as well as the 25man Alizabal. It's still quite sloppy and i'm working on the macros for 5-8 but thought i'd share it first for those that may be interested in going up to 25. I tried gearing up my tank and healers first and as you will see most of my DPS is still quite low (most of them still have some blues and wearing cloth pvp gear just to get up to 372)

LFR Dragon Soul Boss 4 Hagara the Stormbinder -http://www.youtube.com/watch?v=BMu4e4ERyVA
It seems like the LFR25man is still much easier than the 10man normal but I still wiped quite a bit on boss 3 in LFR.
Hope this is interesting!
