You need to end the arena season sooner with the release of T5 in 3 days. Otherwise at the start of season 2, ppl and specifically rogues who likes pve gear in pvp will have farmed T5, SSC and TK for 5 weeks. And by the time you buy your first season 2 gear piece... yeah.
Atm there are almost only rogue teams in the active top 10 2vs2 ladder. With the current release schedule rogues will dominate even more...
Please reconsider ending the arena season sooner with the new raid announcement so we can have a better and more balanced pvp scene. Pvp gear is already lacking behind the pve gear and it will only get worse.
