Questions for Knight Build for Chrono
Knight provides you with toughness, which is what you always want to avoid in raids, unless you are playing the tank. Even in that case a whole set of Knights gear seems to be a massive overkill. You should consider only changing one or to trinkets to knights, in order to get the aggro.
I have also seen people using Commander stats on their armor, which might be another good idea, since +100% boon duration is something you are always longing for as a chronomancer in raids.
