Ugh, will have to remove this glyph from my Goblin.

She has Krush, who I really would like to be even bigger (Gobbies and their obsession of huge things, and all that), but I don't want my wee little monkey, Amber, to get any bigger. How annoying.
As for the happiness thing, I'm quite pleased, to be honest. Far happier than the auto-leveling to my level, anyhow. With the mend pet glyph, many of those skills had become redundant, and it was a real bummer having to take Guard Dog, so I could pick Taunt for my tanks. Waste of two points, really (not a big deal on a BM, but most of my hunters aren't BM!).
