In Lizbeth's theme of possibly making a lower level temple friendly competition. Weapon usage is already tracked for Dickstarter. Set up a temple based on that. Farming where you spend 4-6 weapons a duel instead of a little closer match-up where you spend 6-9 might have similar effect that the points based on glory earned without as serious downside effects to the established already mentioned in that thread.
So missiles cost diamonds and I don't think I've seen them drop outside of party missions, so that might be a draw back to the strictly F2P player that hasn't earned many from other rewards. But I think it is still within reason. Maybe make a diamond pack that includes missiles with each purchase for those that do spend.
