On a raid there are some 20+ buffs cast. Some overwrite others and some won't. It's not different than any melee or caster clicking off buffs they don't need for their class (KEI for a rogue, haste for a wizard). It would allow the pet master to choose the buffs that would be most efficient for his/her pet.
Jaril, people are hesitant to even post suggestions on this forum because of comments like yours. You'd rather come to quick judgement about an idea instead of discussing it through and exploring the options. If you don't like it, either don't post anything or give information backing your position.
God forbid somebody is allowed to make a suggestion to get the ball rolling and have someone else run with the idea.
