thx for your opinion, i feel that sword mastery adds some attack only but it will be useful when in low levels , 70 attack can differentiate a kill or not. but in the later stages, 70 attack may not be as useful but it still helps. the elemental hammers are because both frost and flame hammers does more damage than the hammer crush and they could spam Frost->flame->crush. first to decrease defense, second to burn, which is not too important but for damage and after frost and flame the monsters will stand back up use crush to stun them and use frost to knock them down again.
Well, thats what i think about it =)
