Here's the thing peoples.
In the beginning, Light > Dark by a long shot.
Now, Dark > Light by a long shot.
Now its Lights turn to get a buff. I'm sure they are mulling it about and working on it. My spidey sense tingles whenever I think about how bad Light path is for monks.
I will also state this: The answer to the balance issues IS NOT to simply give light monks a 500 light damage attack or some such foolishness, its just lame.
Extend the buffs based on Monk level, add in a light finisher that converts the monks base damage to light damage for a set amount of time (10-30 seconds) and increases the amount of damage done at that time.
Something like that.
