First of, an ult you have from level 1 needs 4 ranks.

The concept of being able to only cast one spell per target is nice, yet unfitting for a burst mage. The math on e is wrong as well. It ticks 5 times (once at the start and once every 2 second). From the text it says that each tick deals more damage but your total damage is the damage of, not after the 4th tick. Ether the text is correct and it deals (60+15%)*5+(20+10%)*(4+3+2+1)=500+175% or its really just 120+45%. Anyway strange. Just because he cant burst targets, you cant give him one spell that take about 2/3 of a squishies health out. Also riot said they dont make long strong dots for they are unfun.

Why does q deal damgage? Fiddlesticks with an equall ability doesnt and you give him 320 base damage.

Also does cripple amplify the damage he he takes or the one he deals? It seems fine anyway.

Overall i would suggest to make him a support instead of a mage and change his e accordingly. He could have very strong cc with that downside of being inable to lock down just one opponent. The mark immunity should be constant 3 seconds at all levels then however
