MM was great for levelling up, even with the various bugs, when they all get on one target the damage is sick, make sure your using the exploding one on combo fields too.
I didn’t bother switching weapons, liked the staff too much and staff 1 still does good aoe damage when the others are on cd.
Makes all the other classes/specs I’ve tried feel kittened when levelling.
I haven’t really tried it since hitting 80, switched to an AoE/Well’s build for WvW, but I know minions don’t gain any benefit from your gear so once you start gearing up MM builds will get worse.
