Why is Riot "reworking" champs that could just be QoL fixed...?

Like Viktor.

What holds Viktor back?

A) everything about his Q. It's got such an enormous cast time that you might as well never try to cast it on an enemy walking away from you, and as a trading offense+shield tool, it's great! Iiiiif you ever got the shield before you took damage.

B) casting his laser outside the normal cast range causes vik to reposition. If I want to hit an enemy at max range wth the beam I have to be a brain surgeon with my casts, when you could simply make the laser trigger at any point in the full cast range as long as it passes through the vector target.

C) W has a cast time, a set up delay , AND a stun delay. An ability already hard countered by mobility gets screwed over even more by the crippling immobility it causes on it's caster. A burst Mage who has to stop his combo completely to try and land cc. Sounds like it'll be great.

D) R, the spell that's meant to quickly interrupt channels to make an opening for Viktors burst, again...has a cast time. The number of times enemies have leapt out of the way of my "instant" ult is just too frustrating to try and count.

Literally all you need to do is fix some of those. Maybe keep the cast times to prevent him from instant-gibbing but make the abilities go into effect instantly? Maybe quicken the setup time for W? Remove the shield delay? This is all you need to make Viktor perfectly viable. Other than just giving every augment the +45AP rather than whatever crap stats Power and Gravity give. That'd be great.
