While I agree that Ludia should consider new ways of allowing players to earn more XP, I’m not persuaded to believe that such methods will be as productive as leveling creatures up (nor will it swift in its arrival and implementation in the game, if at all).
Based on the current way that the game is programmed, however, I’d argue that there’s another strategic option. I’m at level 9, so my coin cap is 4,000 coins per day. I’m more of a casual player, so I’ve never reached that cap. However, if I was more serious and strategic, I could plan my week out and farm 4,000 coins every day.
So if we consider the following: 4,000 coins/day x 7 days = 28,000 coins in one week, that’s a lot of coins. In one month of saving coins, a player my level could have 112,000 coins saved up.
I disagree with the idea of removing the coin cap, but I understand that it presents players with a dilemma–either saving coin or spending to level up creatures. I think that’s one of the best and most challenging parts of playing a game like JWA.
