--Allow Dismiss pet to be instant (for those frequent times your pet gets stuck in the geometry, or you need to quickly FD to save your raid and mass res)
--3-4 second timer to replace the dismiss pet timer
--Allow this ability to be used out of combat
--Allow this ability to be used in parts of the world that have the slightest little bump. Too many times have I used this on a ramp, steps, near a rock, etc, and have literally not moved an inch.
-Aspect of the Pact/Cheetah
--Make Glyph of Apect of the Pact do what Glyph of Aspect of the Cheetah does.
--Remove Glyph of Aspect of the Cheetah.
--Rename Aspect of the Cheetah to Aspect of the <Underwater Mammal>
---Aspect of the <Underwater Mammal> will allow you, and your group to swim X% faster while underwater.
Those are specific ability changes that I could think of, that should be fixed.
Other things that I would like to see, would be one of the following:
-Give Hunters some true raid utility. In a 25 man raid, almost always; we have absolutely no utility and become a strict, raw, mid-range DPS class. Give us something that no other class can bring to the raid.
Warlocks can summon players, setup demonic gateways, bring free health pots, cast buffs (without pets) or battle rez a player, two specs that are the top two DPS
Mages can teleport the raid, brings food, buffs, has a Heroism (without pets)
Death Knights have buffs, can tank, have the ability to sustain their own health
If we do not get some true raid utility, buff our DPS to be equal to that of a DK, Mage, Warlock, Rogue, or Warrior. I'm not saying let us blow them out of the water, just equalize us with the rest of the DPS classes, who actually do bring something to the raid, aside from raw DPS.
