Twenty Five pages, and nobody has mentioned Immaculate Defense yet?
The temptation to poke the hornet's nest is strong. Or maybe it's kicking a sacred cow. I dunno, what metaphor do you think works better?
ID is great, everyone loves it, and everyone gets it. Insofar as balance goes, it's fine. But with rare exception, no tank would ever slot a different Morale 4 ability. They take too many mastery points to get, and they're terrible. The cost for investing in them would maybe pay off if they were Morale 3's, but they can't compete with ID at all.
So how do you buff the other Morale 4's to be equal to or even better (considering they cost 16 mastery points) than reducing your team's damage by 75% for 10s?
