I do not want to look like a rude person, nor demand anything of you, even because it is a free service that you are doing. But when you say you have 2000 requests, few are like AFK Arena, with so many replys and likes. Anyway, it's not impossible, like I said, a guy managed to modify the skills CD, but had to change every time he entered a battle, which makes it not viable, and it is easy to achieve a speed hack during the battle with game guardian.We have 2000 Requests, AFK Arena is only one from them.
And NO Site have a Mod for this Game, so you can only be patient.
Maybe it is impossible like all Games from Supercell, who knows.
