You'll still have your mount (won't be able to equip Maelstrom things on him tho), and I'm pretty sure wolf marks and allied seals will still be there though.

And yes, I definitely agree the PvP ranks and such being tied to the GC absolutely must need go away. Because it is terribad. Horrible. Awful. Very very incredibly restricting and I do believe it factors in to alienating people from PvP - as if the Frontline GC restrictions weren't enough to do that............
