Keep doing normal till you reach 32... Isn't exactly hard ;)... I can see where they're coming from too... Every mob in the is level 33 the majority of them are hallowed... 31 doing damage to a 33 hallowed is just pathetic... Even at 32 I found my damage to be pretty shit against them, I hope 31's do find a way somehow, but I strongly advise to get your shards and reach 32 before you attempt it :)
