Initially I thought it was another hunter trying to say how great it is in Arenas (it's really not, although I've managed to use it to my advantage on some rare occasions), but to my surprise, the content was actually useful to me:
Deterrence deflects Sartharion's Flame Wall.
As a later post points out, your pet will still get hit and probably won't survive, so you shouldn't make a habit of doing it.... but I still think it's great for those emergencies when you realize you've either left it too late to move, or somehow moved the wrong way (or maybe your latency just sucks).
After more forum browsing, I've also found the following bits of info:
- Deterrence is unconfirmed to work on Sapphiron's Frost Breath
- Deterrence does NOT stop physical ranged attacks (no wonder I died to a Survival hunter last night with Deterrence up...)
- Deterrence deflects Grobbulus's poison cloud (not sure if it works if you're right in the middle of it, since it's only supposed to work from front-on)
Not too bad.... maybe I should try using it more often in raids, in spite of the fact that you can't DPS in the 5sec it's up. Would be interesting to see what else it can deflect!
