New FATE System Poorly Conceived

[RynaultB]

This is difficult because it would have to be done on the fly. You can't really scale an NM up or down after someone has started fighting it, and "kill the mobs" fates could only reasonably scale as new waves spawn.

Hate to quote Blizzard on this, but in MoP they introduced scaling mobs specifically named mobs (NMs for FF). As the mob is hit by more players its HP and damage and all that is scaled up. I remember watching a mobs HP go fro 5mil to 40mil in a matter of seconds when each player hit it with an ability.
