I am a big clash of clans player, and one of their options in the game is to use gems (real money) to get needed resources if you don't want to wait to farm for them. what I was thinking is if you really want to craft something but have been looking for a tc or reagent for days with no luck, why not be able to spend crowns in the crafting table to get the rest of the requirements .
Crafted and dropped gear is not available from crowns as a balance. It's available to all players equally, regardless of member or crown player. Allowing players to buy the best gear just makes the game into another 'whoever has the most cash wins' game. Crafting, Gardening, Fishing and farming for gear and ingredients level the playing field to effort based.
