Crematorium

Three points:
1. War Mace damage is not as bad as people think. It also has lots of good survivability secondary effects which allow you to survive encounters which an axemen would would faceplant in. Also the secondary effects are force multipliers to your team.
2. Clobber is an under-appreciated power. If you six slot it 2 Acc, 2 Disor, & 2 Recharge you can stack the stuns on bosses.
3. It's uncommon and I enjoy being relatively unique.

BTW: Excellent guide
