I am a Control Wizard and to be honest, I have a lot of problems dealing with Rogue. Maybe it's because I didn't master my skills good enough or my build isn't good for PvP but yeah... I get smashed all time when it comes to fight Rogue, but HEY - Rogue is meant to counter a wizard right ;). Warrior kills Roque, Rogue…
I believe you need a lot of potions and other supplies for high level dungeons, so yeah gold is quite usefull. Of course you can share with other players, especially those with low level. :D
