I propose we should be able to buy PvP rank ups with Wolf Marks.
1 wolf mark is 1 xp.

This proposition should boost the attendance of PvP as well as adjust the difficulty of ranking.

Example of the current system: You can cap 20k marks and hit rank 10.
What to do with all those points? Buy gear which you will hoard until Rank 50? How many sets do you have to hoard before you actually hit 50?

All of this is for glam, mind you.

Please devs, this is a system that should have already be in place.
