Due to things like character animations vs recast time + small amounts of server delay you're often not ready to actually activate any ability.

Just watch your timing & you should be fine.
As Orin pointed out, this isn't me thinking I used it and it didnt, this is situations where I know it is available, I hit it, animation goes off, no mp resotred and I still have no charges.

Happend to me on smn last night, so apparently its the ability not the job.
