Since the new version requires silver to lure/strike, old VIP 4 privilege will be useless. I would suggest that the VIP4 halve cd lure/strike change to halve the silver to lure/strike.
Luring/Striking one thousand times only cost 5 Million silvers. Some players got plenty of silver to burn so cutting it into half doesn't reflect the old main selling VIP 4 feature. Here are some significant privilege that matched the old good feature:
a) Unlock Boost Recruit Troop
b) Unlock Mega Feast (Increased By 1 Every 2 Hours)
c) One Recruit Order replenish full troop regardless of troop size
You can't omit old VIP 4 best selling feature and do nothing to replace it. Give it a thought GM.
