Most of the locked jobs were for the first few weeks of savage where PF parties had legitimates issues to meet enrage requirement, so locking jobs was seen as a solution.

Now with the recent melee buff I can see groups locking 2 melee spots because they are so far ahead of everyone else. But with 2 melee and the current gear you can meet enrage with any 6 players left.

Speedkill group on the other hand will probably figure out something like 3 melee + BLM or 2 melee + 2 BLM and I hope they do because thats sadly necessary to help SE notice the issue we have right now.
