No, not if I recall correctly. Since Mace Mastery uses the Arachnos Mace model just like a Bane's primary powers I think they integrate. But I'm not entirely sure on that.
See what I did there? 
Wanna play a Peacebringer? Don't believe the hype. Check out my guide and get the real truth:
PEACEBRINGERS SUCK!!! (Now fully up to date for i21+
) Initially Banes had redraw between the normal mace and the patron mace, but later the devs fixed it and Banes do not have any redraw between normal mace attacks and patron mace attacks.

yep, no redraw. hard to beat the bane + mace mastery combo.

One of the only things sweeter than seeing EXECUTIONER'S STRIKE rise over your victims' heads is following it up with Shatter Armor and amping up the world of hurt.
Rule number six of an empathy defender is NEVER underestimate a blaster's ability to die. I don't care if he has CM, Fort, both RAs, bubbles (both FF and Sonic), and is fighting next to a Storm defender with hurricane on. If there is a way to die in that situation, the blaster will find it.
If one choose mace mastery for a bane's patron pool, in order to utilize both shatter & shatter armor in their attack chain, does it make the bane redraw or change clubs if you activate both powers back to back?
