New champion idea

I want a champion like jayce and kayn where it's ult is like a jayce ult and you press a corresponding q w e and gives a new set of skills. You essentially have 9 abilities that you need to switch around for each situation.

The q form would be a high movement form with low base and scaling damage it would change the e into a short dash that resets itself if on the end of the dash the enemy has no vision on you if used again it goes on a longer cooldown the q in this form would be similar to an ashe arrow but it wouldnt save an extra charge and would take mana based along with a percentage of health on use your w would be a shield based on a percentage on mana and the longer you charge it the more mana and bigger the sheild

the w form would be a cc form where it would be similar to leona but without a hook the q in this form is an auto attack empower/reset that stuns for 1.5/2/2.5/3/3.5 seconds. the w in this form slows nearby opponents and reduces incoming damage by 10% scaling into 20% when maxed out. the e in this form is a 3 second buff appliable to a teamate to prevent them from being able to be cced but cannot be applied to themself

the e form would be a high damage form the q is another auto attack empower/reset but instead of ccing would give more damage. the w is a short range projectile stopped by minions that has an extremely low base damage but high scaling and gives sight on the hit enemy for 2 seconds. and the e is a long cooldown short cleave that blinds hit enemies.

the passive would be everytime they use an ability it would reset their ult but subsequently doubling the ults mana cost until it is not used within a specific amount of time

gimme your thoughts as well as ways i can change and/or improve on this idea
