If universal evolve is not possible, there should be an option to craft evolve fragments in Magic Academy. Currently there are multiple evolving buildings on offer and 0 evolve fragments. It does not make any sense.... FS adventures could give blueprints as awards, which are far more versatile. Evolve fragments as awards (unless they are universal as suggested) do not make sense either. For example, if blueprints are awarded during FS adventures, they could be used in Magic Academy not only for RRs but to craft evolves as well.
My suggestion would allow newer player to catch up, craft evolving buildings and build then if they wish, or use blueprints to suit their strategy.
This game has too many limitations already, no wonder why so many inactive players who abandon this game... Why not to make this game more interesting and engaging?
From the commercial perspective, developers always can offer an option to purchase items which are rare and hence generate the required revenue.
