Campaign Suggestion: Buy regal shards with gold, limited per area

I think regal is such a powerful crafting option for power progression in the campaign that I think it should be purchasable with gold...or at least shards should be. Maybe a limit of 1 or 2 regals worth of shards per area per league?

I think this would help in a number of ways but mainly giving a better NPE and belter progression options if you're stuck.
