I've got to ask. How do people generally feel about Arm of the Destroyer? My only experience with it was in Beta (don't currently own the game) where I found little to no use for it.

Has anyone managed to bring out some of its potential yet?

It's an AoE ability. If you are hitting 4 or more targets you are doing more effective DPS than most of your other oppo form skills. The silence might be useful as well for mobs that are affected by it but as a on-demand interrupt it's useless considering its on the GCD and requires you to be oppo form.
It's also handy for tagging mobs in fates since you don't need to target a mob, just spam this as they are spawning in.
