Lots of great ideas here that Iād like to try out in the future 
I actually have another support build I made early on: Ultimate Harcore Tactician- The Harmacist
Might revise that one day, since I have recently had a new found respect for the Inquisitor Seal line and would like to integrate that into my build ; the damage absorption from there can make a tank into a living fortress and actually increases the durability of squishier builds to a noticeable degree
