On a similar note, do I need to have leveled up in PvP before trying Frontlines?
Just I never really got into the Wolves Den, played a few rounds after 2.1 came out but my Warrior was useless thanks to Sleep magic (seriously why was that allowed!) so I didnt play again.

I'm PvP rank 2 0_o
My current PvE iLevel is ilv85, wearing all i90 gear/accessories with an i65 weapon - would that be ok for Frontlines?
