The data chunk doesn't input into the current version of Mids' Reborn (version 2.6.0.5) so I'm not sure what your build provides. Can you export the short-form build?
This is the version I'm running (almost completely built) with the anticipated Incarnates. For the most part, they are to taste, but I think /Dark benefits from Clarion for the status protection more than Barrier, being more in the camp that "pets are [relatively] cheap." Having both crafted just makes the MM that much more durable and flexible. Hasten is ~3.5 off of perma, allowing for all the secondary debuffs to be used much more often. Hopefully, it provides some ideas for a direction you'd like to take. While this build uses Soul for theme, Mu is likely the better meta for energy resists and the superior AoE immobilize. Mace provides a nice S/L/E shield, but Power Boost's effect is mostly wasted. Ice has a similar S/L shield (but lacks energy protection), but the health boost is very helpful for BG mode soaking.
P.S. The Overwhelming Force KD proc in a tier 1 pet is surprisingly the biggest survival tool for masterminds to come around in quite some time.
P.P.S. Here is a link to the latest Mids' Reborn, compliant with the Homecoming servers:
