Hello!
Today Minneas costs 2 Instance Coins to buy, but today Thanos Equip is a very good but yet a mid-game gear, and to enchant it we need like 2100 Minneas if I'm not wrong. For a player not end-game geared, the Instance is impossible to solo/finish, just with a very well-built party, so it's worth more to craft an army of Alts to farm until you get to Tiara.
Making Minneas cost less in the Instance Coin should help a lot the player in the mid-game to achieve the enchants on the Thanos Hats.
This should not be a problem, since other very good and better enchants as even easier to get.
Also lowering the rate of 50:1 for Sakray itens for like 20 or 30 would make a lot of sense, since it's a mid-gear.
