Uh suggestions usually dont get done instantly. The thing is that I think prices are balanced for certain reasons and that increasing the price just makes it almost donator only. Think about it like this, if we make a dragonfang cost 15k each, then donators(mvp+) easily have 1 mil+ but the average player doesnt have near that then raiding becomes a donator only thing. Its almost impossible to reach a high price unless we make it an extreme thats expensive for donators, yet that makes it almost impossible for anyone else, and crippling for donators but still possible.
if you die with a dragonfang while raiding a base (as a donator raiding a non donator), the non donator earns a dragonfang which they can stowe away. something being expensive but it is something that you are borderline forced to buy makes it fair, because overtime you will lose more and more money from having to buy dragonfang after dragonfang. the only problem with this is going to be a mk2 situation, in which many people (ex me and magic) stored away many mk2s when they were added to #16 at 5k. the price was then buffed to 25k, so our vaults became 5x the price.
Yes but again, this is a direct advantage to donators as they can also kill people with dragonfangs, so they can kill people for dragonfangs like non-donators, PLUS they can buy them easier.
Kitpvp is not a valid argument for any pricing, as money on kitpvp is not given based on donating and everyone starts with a base of 50k, plenty to get kills and start earning money by ranking up. The average player can also convert bamboo from kills into experience, making xp kits not as useful. Then the normal kits genuinely aren't used by most people because buying stuff lets you get better gear anyways. Kitpvp cannot be a valid argument for things done on normal pvp.
