40 Debuff slots in the expansion

Then again, what with the new 25man cap in xpack instances you wont have more then 2-3 shammies and 2-3 pallies in any raid really.

I feel the same way about locks currently. The mechanic held back locks when there were more than 1 or 2, but now with the 25 man groups, you won't have more than 2-3 so it becomes much less an issue just based on that.
