We don't need to be extreme, we can just limit the amount of uses per season of the Trail Mix, as for the price, it really needed to increase, the question was about how much, Going from 0.67 to values like 5 or 10 Golds would already multiply the price of the item by 10x. Isn't there really a middle ground that makes sense? I comment because I care. This project has always stood out for its transparency and dialogue, which is why I brought my suggestion

paying 100 golds to have 15% boost have a sense in CC CL

Players complaining but Nicmo need to find funds for rewards.

i vote to keep it, no one will use for standard match

maybe you can add a formula for the final price -> lowest league (C an D) /  and final cup + CL + CC -> rise price

Kit for red card : unfair

Kit for injury : keep it but only to reduce to 1 day

Kit for 1% energy : limited to 5 per day
