Wouldn't Pet:Haste go up a couple of ranks? I mean, while white damage isn't what pets are there for, it's still useful for building TP between charges, right?
As far as building TP is concerned, this category would only be useful in a practical sense if:
a) Your charge timers are 20+ seconds each
and/or
b) You have an Aymur.
Regarding white damage, you're right that it's probably more valuable to have some haste versus a nominal amount of enmity.
