It's all dependent on the weapon whether or not that mace is better
than that axe or staff.
At 54 I'm using the 2-handerd Gatorbite Axe I got off of Rotgrip in
Maraudon.
I picked up a Blanchard's Stout, 2-handed mace, in the Auction House.
I used this before I got the axe.
I got the Resurgence Rod reward for completing something in Maraudon,
but I don't care for it much. I'll use to keep staff skill up.
I don't use 1-handed axes.
When I equip my shield, Gizlock's Hypertech Buckler, drop in Maraudon
off a goblin Gizlock, 1800+ armor and some stat bonuses including +5
mana regen, I still wield my Hammer of Righteousness that I got in the
Scarlet Monastery. It's got a bonus to healing. (If I'm tanking I'm
more interesting in healing than damaging.)
You'll want 2-handed weapons for the dps, but you'll want a great
shield and a 1-hander for other times.
I'm not an instance farmer so I'm not sure if there's better stuff out
there for me, but I'm happy running with what I've got.
