It’s a great feeling when you get a great blueprint after fighting one dungeon a hundred times. That feeling then gets crushed when you realize you accidentally used it on a seasonal character, essentially wasting it.
Especially considering the fact that seasonal missions have rewards like ancient schematics, it is way too easy to accidentally waste a great blueprint on a seasonal character.
Very simply, the solution should be one of 2 things
1: when you use a blueprint on a seasonal character, it automatically unlocks that forge recipe on no seasonal characters too
2: at the end of the season, all unlocked forge recipes carry over to normal forge, like vault storage does already
It’s unfair to the players who want to use their hard earned seasonal blueprints to have them lose it at the end of the short season, and even worse for those who used it simply because they didn’t realize it was the right character.
