Does it make sense for there to be an increase in the price? Probably not. However, going from 12 diamonds to 15 diamonds wont make a huge difference in the long run. The way I see it is, a level 3 diamond gen will give you those three extra diamonds in 7.5 seconds. A level 2 will give you them in 15 seconds. Even if you only have a level two gen, 15 seconds is not a long time to stall a person while getting those diamonds. As for a price decrease, here is why I think that punch bows should not be less than in regular. The power 3 bow which is the 12 diamond bow in OP is not very good. Sure it has some uses (a.k.a. killing an anti-kb hacker) but it is overall terrible. If punch bows were to switch with the power 3 bows in terms of price, or even for the punch bow to be less than 12, you would have a really good bow for less diamonds than a not so good bow. Does this make sense to anyone else?
