Mall token and some more suggestion

No pvp (kingdon doesn't matter at all as it gives almost nothing) doesn't mean that there is no difference between between players who pay or not.

From this source, we can say that this game is a pay-to-win game.
Paid players can almost do everything faster compared with free players.
For example, a player with a lucky dice, that item that doubles your kill counts, and that item that halves your kill count required to open a treasure chest (can't remember them all).
Their speed to get a chest is 4 times faster than you.
Their reward is 2 times better than you.
Their total efficiency is 8 times better than you.
It affects when they can doing something quickly when you can't, as a free player.
This game is not popular for a reason. As there is something that you can never obtain without paying (trading with other players excluded as it is not really feasible)
P2W game.
