Glyph of WOG has a ~35% uptime with 4t16 and DP fishing with EFs. So, think of that as ~3.3% damage increase overall.
If you're looking for max, ST DPS, you'll want FS, FW, WOG (with t16 only, ofc).
If you're looking for max, MT DPS, you'll want FW, WOG, Alab.
I use DivProt on quite a few fights for progression, and there are certainly cases for it in t16 as well (Nazgrim, Thok, and maybe Galakras of the top of my head). With the Vial and UbS, it's a ~25sec CD, so that's 40% uptime on 20% ALL damage reduction; not trivial.
Other niche stuff would be HolyWrath (use it on HC LS currently), if anything has elemental adds...maybe Immerseus?
