I love SR, it was my first 50, but I really don't think it's the best pairing for Mace. I think Mace is better off as either Strong and Pretty (Mace/EA) or Strong and Bashy (Mace/Shield). EA and shield can both softcap and bring much more than SR. Shield has moar damage, and EA has a heal and end management.
My second 50 is also an /SR, and I personally wouldn't pair a slow set with it. Since the only thing SR brings is Defense and speed, you need to react quickly if you take a hit... Especially in high-lvl content. For me, this means Aid Self, or an inspiration if I'm taking DoT. My Scrapper's primary is Claws, which has nice, fast animations. Mace has a lot of "heavier" attacks that have longer animations. Plus, both Mace and SR are infamous for heavy end use. You could mitigate this with Elude, but I hate Elude. The crash is beyond debilitating, leaving you with less than 10% defenses and a poor excuse for resistance inverse of HP. If the timing is extremely poor, you could wind up in the middle of a mob with Practiced Brawler almost out when the crash hits. Never pleasant.
Still, I'm curious to see how well it works. Let us know how it goes for you.
im planning on making a mace/sr. and you dont need aid self for /sr unless ur planning on solo av's, considering that a green insp is almost just as much hp as it and it frees power slots
Axe/SR is even better, especially with the tons of knock downs included for further mitigation. The only issue I ever had with it was endurance.
The crits on this are AMAZING. I highly recommend this as a solid set. I will get to work on making a build for feedback as soon as Mids gets the update.
