Firstly I'd like to state that I am a decent PvP'er. I do not rage quit etc. I am usually top 3 in ranking at the end overall.
Problems I see:
Healers need a major debuff in the 50's bracket. A fully geared healer can take anyone at all easily. ANYONE. Interrupts only last a few secs which is more than enough for them to re heal to full health, DoT you up and continue to laugh in your face.
Champ Bags. I have been through literally 56 bags and had only 5 pieces of gear, 2 of those being dupes. How is this right?
Sith Inq's Shield needs massive nerf. This is more OP than almost anything in the game. With proper talent specs they can withstand 10k in damage. Little cooldown.. bad idea.
Why not bracket PvP into 10-19 ,20-29 , 30 - 39 ,40- 50 This should clear up most Que issues (long que times are killing the pvp during the day)
Still love the game, just not the PvP system yet...
