What if GF/RW made the whole peak thing worthwhile. Right now, it is my understanding that you only get like 3% increase in attributes at P5.
I am going to throw some numbers out here. I think they should be higher that I am going to suggest, but I am confident TPTB (the powers that be) will want lower than what that much work should be worth. Remember, again 65,000,000 Peak points is actually equivalent to 6,500,000,000 regular points. My toons that are level 100 but not doing peak show that to get to level 101, it would require 110,389,000. from peak 1 to peak2 requires more than 58 times that number of regular points on that 1:100 point ratio.
To make it worth doing, how about each peak level gives primary class +2% physical or magical damage )as class appropriate), +1% attack and +2% physical and magical defense. Peak10 would mean about the same as over-dura gear.
