Good morning sir. I have some suggestion hope developer will approved this.
1. wing Exchange - a 1 time big time event that could let player exchange same level of wings to other class wings. why? First of all you release the patch too late. Many player fuse wing and get random and then you release the new patch that let player choose the wing they want to fuse. 2nd,the drop rate of Phoenix spark not that good. 3rd , success rate is 50-50.
2. Lapis Exchange. - let player exchange lapis but ofc not the same ratio. it like 3 athena B = 1 ares B or 1 nereus B. something like that.
3. Discount on Dismemble or make it free for VIP player - Since you greatly reduce the gold reward on Land Defense NM , but you forgot to reduce the gold needed for dismembled and Claim rewards on Elite challenge.
Thats all for today sir. Thank you.
