It’s pretty much agreed upon everywhere that a 3 Glimmer Haste build is currently where it’s at.
I find it pretty difficult to chose it as my preferred setup: sometimes it’s just not even in the best alternate setups, and then the gem or item choices can be dubious. The build is described here: https://www.wowhead.com/guides/holy-paladin-glimmer-of-light-build.
See https://www.askmrrobot.com/optimizer#us/medivh/ainsley for example.
This keeps suggested a 385 sliver as one of my best trinkets, even though Glimmeradins are in melee range most of the time and then the trinket effect won’t trigger.
Anyway, hoping for this setup to be easier to chose and customize without obvious defects if possible at all!
