Sure PvP Rank 'may' not change 'that much' (unless they don't significantly rebalance the current abils/traits... the traits are extremely significant)...

But it's more for me about unhindering the ability for us to play with our friends, period.

I'm about Rank 30 now, regardless how much bonus xp Frontlines gives, heck no am I about to start from scratch. Or impose a friend begin anew... that's ludicrous.
