Please don't make upcoming arcanes common weapons. Current mythics are already way too easy to obtain because people just open locked chests and pump op gear into the game, perhaps arcanes should be obtained through other ways (like glintstone set back in the day). I really preferred 200m price tag on mythic bow, its a very powerful bow and should be very rare and expensive.
Id also like to point out that I was unable to afford that bow when it got released, it gave me motivation to play again in order to upgrade my gear, however after just few events price dropped to 30m which left me with 0 purpose to play again.
