I'll join the club.
Cloning is bad. It makes legendaries unlegendary. It gives you infinite items. Clone rare candies: you levelup with them. Clone masterballs: you can catch Aruseus, Rayquaza, Mewtwo, etc. easily. Clone nuggets: infinite money. You can clone 520 pokemon and put them in your boxes. Think you can pwn with them? No, you can, but people will not respect you and will think you are a loser, no matter what you did, even if you pwned 5,000,000,000 trainers. Clone is for cheaters, and I'm not cheater, so I don't clone.
Well, you can lose your own pokemon cloning. Think about it, you accidentally lose your Lv. 100 Rayquaza (with max stats and powerful moves) while cloning your useless Lv. 5 Magikarp...lol.
I'm against cloning!!!
