Quite an interesting post, but mainly more because I was looking for more info on how to tank better.
I've only just got the provoke skill on my GLD and noticed the cooldown was pretty long, so I assume shield lob is a good way to aggro initially, and flash is good aggro/crowd control in the immediate vicinity, while provoke is kind of more for emergencies?

Would provoke followed immediately by a shield lob help if provoke only puts you 1 emnity point ahead of the DPS who drew aggro? I know the DPS needs to back off but taking into consideration the time it takes them to realise that I'm just thinking it's a emnity-generating ranged attack with a short cooldown and might put you a little more in the clear quickly. Good or bad idea?
