You know how frustrating it is to mine quartz or kill mobs on a mob grinder to get experience. Well I personally think it just takes too long. I bet a lot of people would agree with me. Now the thing that I thought of was "what if we could buy levels?" And that is what Im recommending, add buyable experience bottles on the shop or what would be even better, put buyable levels next to the enchanting tables, Ive seen this on other servers, where you can right click signs and it substracts a certain amount of money from your balance and gives you a certain amount of levels. It would make life easier for a lot of people who are set on money but are forced to mine or kill mobs for levels.
