Ok the following have been tested on my normal draenei shaman:
Flametongue Weapon ranks 1 through 7 teleport caster to innkeeper.
Ranks 8, 9 and 10 dont proc anything... so they might proc the same bug, i dunno.
Also my enhancement shaman's Maelstrom Weapon isnt showing up at all for the past 2 days. Havent touched my talents... dunno what happened.. i will try to reset my talents and see if that helped with anything. I will keep you updated.
