Canonically, Holy Paladins have to spend three talent points on ToR, which gives one Holy Power whenever you Divine Light your Beacon Target (I like to pretend that Flash of Light doesn't exist). This is sort of a deal with the devil; One HPwr in exchange for a 33% reduction in throughput (due to the loss of 50% Beacon transfer). I'm curious as to when it became universally accepted that this is a good deal and worth three talent points.
In my World of Logs (example) I consistently see ToR provide pitiful HPwr returns compared to Blessed Life, Holy Shock (obv), and Crusader Strike. I run three Holy Paladins in our 25s so it's possible I can afford not to heal the beaconed target since there is probably another Paladin direct-healing him. I understand not everyone has the luxury of being able to trust the rest of their healers, but just throwing this out there...
ToR encourages inefficient healing practices and costs talent points that can be used elsewhere. I don't think we should be so deathly afraid of RNG that we jump at this talent just because it can guarantee Holy Power generation on demand (with a slight and intensely annoying delay). I'm trying 2/3 this week in raids and I don't know... maybe I'll hate it and recant this whole idea but really - just wanted to encourage everyone to challenge conventional wisdom and try new things, and of course to share their opinions/experiences regarding the subject.
Also my little pipe dream: Blizzard runs reports on least-used talents and if everyone decides it sucks, they'll eventually change it.
