Before 5.0 jonin medal was a good investment because by doing it on a renewal week, like this one, you used to get for 1888 ingots spent 4100 coupons back in the 180 days (20 per day + 20 more once per week on Saturday) and 944 coupons from the renewal itself, so the ratio was: 5000/1888 = 2.6, that was actually comparable to running additional convoys if you were in a server you could be plundered for or if you wanted to do the try your luck wheel and since there were all the secondary features (base stat bonus, world boss boost, sweep of exams, daily practice packs instant, 2 more lineups, etc...) was indeed worth it.

The problem is that now is no more so because the 2nd monthly card is simply too good in comparison with (6 times the give back ratio) and the same is the top naruto froggy (not much for the ratio, that more or less is the same 2.7 times, but for the time required to get the full advantage: 7 days).

Jonin medal since 4.0 was supposed to grant to the users a 10/20/30% discounts in black market, shop and eventually on some weekly events (by granting 20/30% discount vouchers in the events that had them preset as potentially available choices, like 7 days of welfare one).

Was supposed to give access to mysterious treasure and to a specific shop (the one in east konoha).

The reason why is bad right now is simply this one: you did not implement anything of this.

So, if you want to go on avoiding to implement any of these things, at least make the medal worth it (increase the coupons per day to 50 or change the weekend pack to grant 200 coupons instead of 20 or cut the cost of the medal to 688 ingots or make the coupons gained in this renewal event not the 50% of the cost, but 200%).

If you do not do any of those things expect to get a very massive flee of people like me and regn from this investment.
