Much have been said about the imbalances in World of Warcraft. Most concern the different classes and how it feels like Blizzard is favoring some over the others. At the official WoW Forums for Europe, a post regarding Hunter and Arena revamps is currently gaining a lot of attention.

A WoW player under the username "Lanfear" gave a lot of hypothetical improvements that can be done to Hunters. It included changes in skills related to Beastmastery, Marksman, Survival, and others. Luckily, the thread was picked up by blue poster Vaneras and answered:

The developers are looking into the whole Hunters in Arenas situation because Hunters are somewhat under-represented in the Arenas. When that has been said however, I do not think that we should expect to see another complete Hunter class revamp. At least not before the next expansion that is.
