People supporting this freegiving away of arena gear in Cata use the fact that people in Arena must be able to easily acquire their gear in order to prove their skills.How about this idea then!"Provisional"arena and battleground gear.
Within a designated,instanced area(this will take a load off the servers too) called "War Bestiary",available in each city,there will be vendors,selling for a small price,copies of each season's finest PvP gear.This gear will be called "Provisional XXXX item"(where XXXX add the pvp item name of your choice).
Provisional gear will be carbon copies of the best available PvP gear this season-only they look plain and bland,like leveling items.You can bring gems and enchant scrolls in the War Bestiary in order to enchant/gem them as you wish.There will be a little banker NPC holding a 30-slot bankspace in order for you to store them.
Provisional PvP gear will be only usable within Battlegrounds or Arenas.During Arena prep time there will be an exception to the"no equipping items"rule so that you can equip your provisional gear.
Of course,proper Gladiator gear will be issued regularly,with personal rating requirements etc etc.Nothing will change about them,they will be epic-looking and properly usable anywhere like any item.
So this will keep everyone happy:Everyone will be able to PvP with the best arena gear at any time,while skilled gladiators will be able to strut with the shiny,epic looking versions of them outside of Arena/Battlegrounds.Everyone will be issued the best gear to have a chance to win,but only the ones who deserve it will get their shiny versions,and use them anywhere they wish.
