Great idea, but needs tuning up
This is really a great idea; a super simple interface for a reasonable complex system. However, there is something that bugs me--elixirs. The way they work is perfectly fine, but when we buy one while we already have one in our possession, shouldn't one of them be automatically used? I mean, that just makes too much sense to me. Instead of just wasting money, why aren't we allowed to use the old one and buy the new one? it's the only time you can actually lose money without getting ANYTHING back, so I think it's important that you get something for buying an elixir when you already have one.
