Oh yeah it does that...

When putting together the previous post I initially was going to state that druids didn't have any interrupts. Fortunately I was asked to tank Arcatraz (all the way through which was a novelty) for one of our mages who was keen to get his Sha'tar rep to revered for the glyph.

Whilst tanking Dalliah the Doomsayer our plan was just to dps through the heal due to lack of rogue/shaman. As I got out of Whirlwind range the dps did the best thing whilst the boss isn't being actively tanked, and continued nuking. So to get back in quickly I used Feral Charge hoping to either keep the stack of lacerates up, or get it back quickly enough. The mechanics of the fight mean that she always casts heal straight after the whirlwind, and as I shot back in faster than the average bear I noticed the heal fail to complete.

D'oh, /facepalm, time to cut up my tanking licence, I forgot about the interrupt component of the charge, mostly because of the amount of times I charge at something that isn't casting, or is immune to the effects. I'm sure there's been others, and it's probably only going to get worse as the next expansion (and probably the following ones) introduce new abilities.
