Champions Rework.

I was thinking about what could be the next Champions rework going to be,Maybe ,,,,These champions need a rework or changing some abilities or work on damage,Singed Q takes 13 mana at all ranks? why is that!!,It should be 8/9/10/11/12 or 9/10/11/12/13 that would be better,Sion i don't see that his abilities are good for him,1 year ago he was AD champion but now he is AP champion, This is crazy,He needs a new abilities that conform with his character,Talon needs a new passive i am very sure with that and his W you should work on it,Kog'Maw needs to work on his abilities damage and i think that he needs a new ult,An ult that cant be used every sec,Here is what i was thinking about: Fires a living artillery shot from a great distance that lands 1.5 second after launch. Deals 120/190/260 (+75% bonus Attack Damage) (+55% Ability Power) magic damage and reveals non-stealthed enemies for 3 seconds (deals 100% bonus base damage to Champions)(deals 150% bonus base damage to minions and monsters) Cooldown:22.5/20/17.5 Second Mana:70/85/100 Range: 1250/1500/1750 Area of damage: 250 or 300(what ever you see it is best for it)
