Hi! Unfortunately, I do not have much in a way of changing how content is activated (this is not part I control), but you can contact me on FoundryVTT discord (if you ask for Rughalt / Dragonshorn Studios moderators will point you my way), and I think I can either help you or issue a refund.
Hi, would you care to elaborate on which aspects you thought were especially unbalanced? I would like to be able to balance this idea as well as I can, so if you can provide me with a few details about where you found issues, that would help me a lot.
Sorry if you thought it was lacking in creativity, too. I tried to base these designs on the Unearthed Arcana document as closely as I could and not stray too far from the established pattern laid out there, so if some of the abilities are a bit similar to each other, that's probably the root of it.
I also wanted to follow the impression I got from the UA that the Master Runes represent fundamental aspects of nature, so I didn't want to delve into abilities that got too wild for the first draft.
Again, if you have any more detailed criticisms about which parts you're referring to, I'd love to have some points to work from.
