From today's blue post:
An update for paladins: we're going to buff Word of Glory and slightly nerf Light of Dawn.
I honestly do NOT see a need to nerf LoD, even if it's a "slight" nerf.
The reason I say this: it's only limited to 6 targets!
If they're trying to force us to use Holy Radiance, well, I'm sorry - but that spell is so situation mainly due to the fact that the spell effect only has a 10 yard range! It's almost worthless in some 10m encounters.
I for one am not looking forward to this nerf.
