-taunt should work on bosses. it's total BS that priests can get a 150% exp boost whenever they want, but a shadower can't get a measly 40% exp boost from a boss if they want it? MAKE TAUNT WORKON BOSSES! it used to!

Priests do NOT get a 150% boost if they are by themselves. it's 110% if they're alone. So no, they don't get it whenever they want. Even in a party of two... the total best exp possible that they can get is 110% of the original... it wont go higher (that's after adding in the party bonus exp). It's only major boost if there's a party, meaning everyone in the party gets the benefit not just the priest.
