Now a days, people just grind JK and FSC or crowns. Otherwise, they do prestige missions for prestige. So then what use is there in adventuring in arcade?

Ever since missions were introduced, most knights stopped bothering going through arcade, and just do the missions like king of ashes. Hence, the fun and adventure has been lost. People don't do arcade simply cuz the payout is a lot less.

My suggestion is simply to increase the payout in arcade, and decrease the payout in missions such as vana and jk. Or add some other benefits to arcade to make it worthwhile.
