The following is solely in my opinion and I'm probably partially biased but:
I think Light is going to end up being weaker than Dark at the rate its getting clipped, holy warrior only beats unholy warrior because of immunity and weight and Dark does not have to beg for a style of match of their choice.
Also dark can at 3rd tier make 5 point strikes (rare admittedly)while light can only make 3 points , admittedly light can dodge an immunity once (mastery) at 3rd tier which is an edge but I'm beginning to wonder if it really stacks up so well against everything else.
At higher tiers Mind Thief is far superior to Right of Domain since Mind Thief grants immunities with each win. (the final score with both maxed out would be Dark 7 Sig Styles + 3 effective Locations vs 5 locations + 5 effective styles at 7th tier, Admittedly by using both Holy Day and a Purity of Focus (to stop Dirty Trick) the light could choose an immunity but thats burning a few abilities)
Also the sheer number of Honour followers makes me wonder about just how balanced honour is, it has the most followers of all paths at the moment.
All of the above is IMO and should be carefully considered before being accepted, or alternatively my opinion being what it is should be instantly rejected.
