Choose one, please.
A) If you are dispelled, the first (top) 3 buffs you have loaded are the 3 that you will lose first, so it is imporant to buff yourself with junk buffs before loading the really good stuff, so you can keep it in the event of being dispelled. Keep an insta-clicky handy in case of said event, to restore junk buffs.
B) If you are dispelled, any and all buffs can be lost, as the dispell script is at random. "Loading with junk buffs first" is no longer valid, and you can either get lucky, or be unlucky. If insta-click buff was dispelled, you can reload using clicky, which might lower the percentage that a "good" buff will still be kept.
C) Both A+B, depending on mob.
Now that you have made your choice, please post your reasons, or actual links/text that can back you up.
Thanks, in advance.
