It is a very important of feral druids received buff in 3.0.8: further reduced shapeshifting cost with the new Primal Tenacity. This virtually makes a feral druid impossible to OOM in any situation, ever. Every other mana-based melee hybrid runs into mana issues except feral druids now. In fact, it feels like they have become the original 3.0 paladins that had endless mana pools with the 33% judgements of the wise that later got hotfix nerfed about wow gold.

I will not go to argue about their absurdly high damage to do not get me wrong, because quite frankly they need the high damage to kill things given their small amount of interrupts, stuns, and peel about wow gold. However, the fact that it is literally impossible to ever run them out of mana now and given that they are incredibly hard to ever focus by any team, and you have one of the strongest DPS classes right now, especially when supported by another class that offers a healing reduction to get wow gold.

Warriors suffer rage loss and inherent stance penalties when they change stances; Death Knights take a 10-second rune cooldown (and also can not swap presences if runes are already on CD); Druids lose basically nothing when shifting to/from cat and bear. I actually agreed with their change to primal tenacity but the new Improved Leader of the Pack is really a slap in the face to enhancement shamans and retribution paladins who have much more severe mana issues to get wow gold.
