lol i have the same thing happen to me i have a lvl 17 life that beat a lvl 30 balance and i got 4 points for the win
and i have a lvl 5th myth that was in 2v2 with a lvl 5th balance and we faced about people around lvl 20 it was a pretty easy match they fizzled a lot and afk to much but when we won we only got 3rd points
I believe they give points based on ranks, another broken thing in PVP. They should give points based on ranks and level. I have four grandmasters two of them Warlords and two are Commanders. I decided to try my myth magus in PVP a level 35. I won a couple against private grandmasters and got couple of points less than 10 each win, at one time 3 points. I managed to get to Captain then I lost to a corporal Grandmaster. I lost 20 rank points.
