Regarding the use of
[Band of the Swift Paw]: I use S3 head and chest in my tanking gear which gives so much resilience that I don't generally need to concern myself with going out of the way in other slots. This flexibility allows me to focus on getting some hit on my tanking gear, which I consider valuable for the OT role that I fill.
This path also makes my gear very good for switching to dps when my mob is down, since the S3 gear socketed with agility is very solid dps.
