Dismissing this talent based solely on the fact it can't be used every single minute on CD doesn't take away its utility and usefulness. The second beacon of light, glyphed, with no global CD would be useful if the beacon spell itself didn't have a mana cost AND if it didn't already have a 3 second CD. Constantly swapping beacons beats the point of refunding 40% mana, it is redundant.
Now, will a second beacon of light increase your HPS? Obviously. With the global CD Glyph, will beacon be more Mana Efficient? Not sure. But, you are overlooking something. At 630+ Item Level, Mana isn't a key issue anymore. FoL spam, if cast on your beacon target will not "oom" you, or at least not right away. Even with no Spirit itemized, Paladin's only really go "oom" when they spam FoL on non beacon targets.
Furthermore, the more gear you get, the more powerful heals get. At that point, it will come down to which healers have the most utility. Paladin's arsenal of utility is unmatched in mitigation and keeping tanks alive.
