Arena suggestion

The biggest problem with arena is the lack of players in there and the frustration of new players when they encounter strong players.
So I would suggest splitting the queue mechanism into 2 - attackers and defenders
Attackers - work like it works now, costs 1 AP, lose points or gain points, gain some resources/xp for a lose gain more for a win.
Defenders - costs 0 AP, cannot gain points, gain resources/xp for a lost more for a win. Being a defender allows more people to take part without affecting other parts of the game.
