Many people do not know this but you can get stat points from pvp ranks
Here is the chart of the number of extra stats per pvp rank: https://2img.net/h/i414.photobucket.com/albums/pp229/GS-Thanatos/Ranking%20Guide/RankSchemeEpisode4.jpg
They are given out per pvp rank at the vet manager in the stardust knights area of apulune.
The extra stats shown on the chart are what you get per lvl on top of what you got the previous lvl.
Example:
If you are rank 2: you get 1 stat point for rank 1 plus 3 stat points for rank 2 for a total of 4.
Not easy to get next rank after rank 5 though
