PVP xp/wolf marks is fine i believe, there needs to be a few long grind otherwise people will stop PVPing again in less than a week.
One slight thing i wouldnt mind if they increased tho is the challenge log for PVP, 10x games & 3x wins per week for 200 xp each is not really noticeable. Should maybe have 100 games and 60 wins for say 1k xp each. Still not a huge but enough to have a slight impact.
