well i think it was a lil overpriced but deff worth having since u dont want to wait on a chance on drop and also u dont have to waste ur dkp.Combine that mace with the offhand from badges and u get a leet combo there, Atm im using Haunting Call which helps me bring my hit rating to almost 12%.
I got it made for 4k ish. And i am happy i did, my guild has cleared everything in 10 man and 25 man at the moment and othing similar has dropped yet. And tbh, I do not think i will replace it with the KTZ mace if it would drop. (looks bleh and is only slightly better).
To answer your question, yes i think you have made a good deal.
My guild has been churning these things out ever since our BS hit max rank. At this point I think we have made at least 7 of them, in addition to like 5 titansteel shields. I cant wait until I actually get to use my titansteel cd for profit
