Sterling had a great idea with the gear bought through the arena.

This in short would give the PvP player base a home, and a fun little side trip from the adventure of the storyline.

I for one would like to fight others to gain gear to help my fighting in the Coliseum.

Even if the gear is stored only in the coliseum with a NPC storage area specifically for that gear, would free up inventory slots as well.

Can even put up server score boards opening up the competition.
