The following champions have become 'clunky'

Should these champions be created to be less clunky and much more fluid in the nature they are suppose to be in?

Needs to auto-attack, unlike Katarina to get her skills off. Good luck hitting that third Q without flash m8 This dude just heals too much. Seriously, ADC's are suppose to be in the backline. This dudes needs to run up to the backline because of his poor range and shoot people down, if he didn't heal his entire HP bar back with his stupid lifesteal he would be gone. No other ADC relies on this stupid gimick. Fix that AA Fix that AA "Maybe if I land my W, then I will be able to not only use the first wave of my E, but also able to use the second part of my E!" Viktor said before he instantly got stepped on by the enemy Assassin; the champion he couldn't contest against in solo damage because they had half a brain to step out of his clunky ass E (I love playing Viktor but . . . man that E gives the enemy team a Sion's Q to get out of the way.) Why does his passive reset 5 seconds after an ability AND have 12 seconds on it? Why not 10!?

Champions that don't suffer from incredible amounts of clunk flow well and feel well to play:
