agree...I think they should change the minimum requirement to 200 or 150 something...But still...its like a recharge event....what can you expect the reward from recharge event if the reward is just an extra.. you can still save up the ingot for the next better spending event.

Here is the calculation : each day you can get mix 150 point included the box point 100 and the mission point 50. so, 7 day = 1050. Mei is worth 5200 in 80 frag. So you left 4150 after the deduction. And so 4150 = 415 box, each box cost 20 = 8300 coupon or ingot.

I am sure that you can buy the school outfit in the future...but not as fast as possible...maybe take a bit long time..the cost is similar to normal outfit for around 2000-3000 coupon. Also, if you are in f2p server while no one will top-up, I suggest you to get one(it just a recharge event). Otherwise, you have to wait until the outfit added to the shop and spend 2000-3000 coupon.
