Every class in WoW has something that they excel at.
For mages, warlocks and shaman this year, it happens to be 3v3. DKs are elite soloers, druids are hit-and-run farming kings, paladins never die... and hunters, well, over the full 8 years of WoW you really can't beat us for levelling/questing (what do you mean, you have trouble tagging and/or killing goats?).
This expansion, however, I've found something else we're good at - Scenarios.
Not only can we solo everything, we're also the most versatile class anyone can be put with, since we can bring 5 different pets and act as tank or DPS depending on group makeup.
As a bonus, the PuG queue times for DPS are short, unlike LFR and LFG... so if you're as sick of dailies as I am and need to top up your VP for the day, it can be a quick and easy "dungeon" where you aren't as likely to wipe... purely because you're the hunter and you can make it work!
