So I tried the arenas and they were fun. I went 2-8 in duels, but I didn’t use a special build or anything, I never ran into anyone who did anything crazy, which is good.
My character is a level 164 mage that really isn’t very mage like in PvP, so respeccing would probably be a good thing.
I did get into a 4 player with summons free for all that was fun. It is timed and when you die you get reborn at full health. Pretty crazy couple of minutes.
