Recently with the double AP as well as previously without double AP, I have found limited use for my AP points. Don't get me wrong, I know I can buy purple and gold items, some gear as well as basic potions and food. I do spend a small amount of AP on food, potions but most of my AP end up going back into PvP activies, e.g. trebs, oils, repairs etc. Even still I have over 200K AP that I'm not interested in spending on gear, purple or gold items (some of which are random). Don't get me wrong, I love PvP for exactly what it is and I don't mind my AP going back into PvP, however, I think there could be more benefits of AP for players to promote PvP to gain AP.
What I'm suggesting here is that some rewards which can be purchased for AP, be implimented into the game. For example some recipes, ingredients, basic motifs, furniture blue prints, just some common things that can be purchased for AP to make PvP a bit more of a rewarding experience.
