I'm also curious to know the following questions. You can completely ignore them or fill them out in your responses :p
What comp will you be playing?
What rating / ladder spot are you looking to obtain?
Do you feel like your comp is strong compared to others?
Are you hopeful that the implementation of PvP Power will remove PvE gear from arena, or do you think blizzard will manage to make a trinket or weapon so hilariously overpowered that it can't help but give an unfair advantage?
