Hey, one of my biggest issues in wow is the fact the Light is pretty boring as a religion (Despite the fact Humans, Draenei, Blood Elves, Dwarves, and now apparently Undead all revere it). It just seems to be Christianity but without any actual prayers or traditions. It has a somewhat vague history that still establishes the formation of the order, but never any actual thing that priest actually do to venerate the light. We might have to get some religous tools or prayer book, but never get to read the prayerbook or see how those tools are used.
Hell the only people that actually explain why the light is venerated beyond it’s historical signifigance are the draenei (Do to having demigodlike beings made of the stuff that guide their race) and the FORSAKEN (Because the cult of forgotten shadows actually went deeply into what role the light played in the universe and why shadow worship was just as vital).
How would you make the light more interesting? It’s not a bad concept being a pseudo-christianity pseudo-buddist religion, but it needs work onto why people worhip it and what it’s worship entails.
