The legacy perks allow you to level faster. Don't deny this - it will be P2W.
I just don't think leveling faster is P2W. Maxing out your character will be done in Operations. An XP boost won't help you there. It will just help you get to 50 faster.
Sorry I meant the legacy perks already allow you to level faster. That is not F2P. I meant buffs or gear normally bought with only ranked WZ credits now available for sale or other random buffs they could offer.
