Frankly, please don't push this forward to the developers? Even if it doesn't free them up to fix old bugs, it does free them up a little to do -something else- anything else would be better than cosmetic changes. I've listed downsides before, I'll itemize it:
1. Developer time, money, and resources.
2. Computer graphical memory (newer models and textures take more.)
3. They may not implement it in a way we like it(We may all get forced to have the same non-racial pet model.)
4. I don't care what anyone 'says' a DPS parser picked up, the DPS parser doesn't know when your warder is graphically freezing, only you do, and I love Babe too much to care what other people think they saw (Scaled warder). Plus, if you avoid situations where it matters, ie: Don't run away from the mob, or let anyone other than yourself and a tank take aggro, congratulations, you've got nothing to worry about on your uber DPS losing bug. If you're talking about aggro kiting, your pet really shouldn't have high aggro procs on her now should she?
Here's an alternate option on something to put forward to the developers, you know how Shadowknights get an innate ability to lifetap, without a buff or weapon proc on, with the touch of the cursed line of aas? How about we get a group recourse aa, short duration buff, 5 hp 2 mana per tic per level, 10 levels, only procs about once per minute before any modifiers, doesn't heal on the first "tic" lasts for three tics, keeps it from being too wicked with multiple beastlords in a group unless they stagger their melee and/or happen to proc at different times. Paragon's touch? *Shrugs* push -anything- other than the pet model idea, I beg of you?
