[TBC PTR BETA] Enable custom testing modifiers inside the arena

Hi,

if possible please make all the beta NPC options available for arena too so players are able to play an infinite game without dying etc to test some stuff better.
Currently you lose all modifiers taken on entering an arena game.

In case there are trolls abusing this to queue snipe which I highly doubt maybe enable it in Skirmish or Rated only up to your liking and not both queue types.

Thanks
