If they do it like they did with Ranks 6 to 10 the grinding won't actually be "that long". if you're rank 10 and 50% you'll probably get rank 12 and 75% when the new ranks arrive. Sure it's still a lot of XP to get no doubt. But not necessarily a pad thing. Even for gear gap. If it happens alike, T1 PvP would be given away and T2 PvP really faster to get for everyone. In my opinion, despite T4 vs PvP gear, the main issue is PvP entry gear.
