pretty good concept but in LoL, mana drain is removed because it is imbalanced in a way since most champs don't have much mana pool as well as most champs don't even have a mana pool. Morello said this himself that mana draining limits a game to have champs that have mana. So removing it and replacing it with either a stun or a slow would be great since it is inline with LoL concept but since you can do whatever you want, do whatever you want >.<

the Tatoo concept is pretty good and is pretty fresh since no champ has this kind of kit wherein he could be both a support mage or a burst mage.
