My team is Druid, Priest, Mage, Warlock, Warlock playing horde on Firemaw EU. Currently lvl 18.

Enjoying the game, been lvling professions a lot.
153 skinning, 115 enchanting. 75 Tailoring. 100 Leatherworking. 131 Herbalism, 97 Mining.
114 Cooking, 91 Fishing.

Did RFC when 2 characters was lvl 14 and 3 was lvl 13. Very smooth run but took maybe 40 min.
Did RFC again at lvl 17. Took ~15 min to kill the 2 bosses that drops loot. I would get ~10k xp per hour if I did that nonstop if I managed to run out and sell in ~5 min. (I think xp from normal melee cleave was estimated at 19k per hour at lvl 15, so I am far behind those numbers but still ok xp)
Although I am too lazy to grind dungeons nonstop...
