A year ago at this time LM didn't have staff sweep, so don't kick the gift horse to hard. We only had one melee attack. I personally like that its AOE, plus it gives me power back.
LM is a pretty decent class and very fun to play. I have way more gripes about my warden than my LM. I pretty much don't have any about the class. I'm not saying its perfect just that compared to some other problems that other classes have, LM is just fine.
