When did you use Clemency? As far as i remember you get interrupted pretty fast. so as long as you're not tanking anything its useless.
Royal Authority, i never said you shouldnt/couldnt use it as MT. but theres nothing more than "you can use it instead of halones to do a little more dmg but no debuff and 0 enmity" to it.
Sheltrons mana is absolutely useless if you dont use halones combo as the only one.
