Works for me. It’s not a substitute for real change, but it’d be nice to have a good source of rare resources if I decided I didn’t want dragons (or if I had sigils left at the end of the season).
I don’t feel like going for this warrior mythic, for example, and so I’ll go for the egg token boost and…I don’t know. Riders, maybe? I have the heavy-hitting dragons I need for now. I might prefer to be able to stock up on embers, timers, inners, energy packs, mystic fragments, etc.
