I haven't seen Silent Wizard on here in a long time. It looks like he is leveling his HK Slient_Wizard first, so you might try whispering him in game and see if you can get his opinion. Considering who you play with, I think you are better off as a Guardian. It fits your style of play better. HK is useful for some dungeons, LN comes to mind, but the tradeoff is losing the hammer. God I hate the damage, or lack of, with a mace. Even with a HG mace, I will hit myself with my Crit buff and switch to my BKR hammer for the 10 seconds the buff lasts, then switch back to the mace.
BTW, gratz on 100!!!
