Nice, I like how this one has a build that I actually just found out about. The full support one I find useful in team fights where I have to dive. I was about to write a guide on it but you beat me to the punch! lol.
Also, it seems that your builds aren't like everybody else's. I find that that is my style as well.
For the full support option and the Sanctification Ult., I'd like to point out that using Battle Momentum with Sanctification makes it somewhat spammable now. The fact that you can up the time and now make it a 25% damage boost works wonders when you're running around with a lot of assassins that need protecting. This combination helps to compensate for how uncoordinated your Quick Match team will naturally be and begins to rely on you using it as soon as you show up to the field instead of at a specific time, which may or may not work, while the shields help to ensure that you survive for the entire time. However, I would still suggest only using this 'Spammable' Ultimate when there are:
1. 2 or more heroes engaging an objective or the like.
2. An enemy ultimate is active/charging against your ally/allies. Thus interrupting or even negating the attack altogether.
3. Or in rare cases to allow someone to escape the enemy team.

Sorry about the wall of text! Hope it helps though!
