Ability button consistency among achetypes

While there are many unique champions in the game, there are also many that are variations on certain achetypes. For the most part, characters with similar achetypes have similar button combos. For example:

• Riven and Aatrox: Q is 3 hit ability, w is some form of CC, E is dash, and R is power up.
• Sona, Soraka, Nami, Yuumi: All have a damaging skill on q, a heal skill on w, and something to do with speed on e. 3 have hard CC on R.

My point is that if a kit is similar, it's very helpful for learning and switching between champions to have similar abilities on matching keys. Which makes it more annoying when they don't match.

• Thresh, Pyke, Nautilus, Blitzcrank vs Leona: These 5 all have a similar "Dive/pull and CC" style. The first 4 all have hook on q, shield/mobility on w, and CC on e. Leona, however, has CC on Q and hook on w.
• CC mages are all over the place. Despite Lux, Elise, Ahri, Veigar, Anivia, etc. all having a single hard CC skill, there is no pattern at all.
• Mobility ADC like Vayne and Corki all have their move skills on different keys.
• AS enhancer adc, like Jinx and Kai'Sa, have their AS increase all on different keys too.

This makes it harder to swap between champs, where other related skills might be transferable. The muscle memory (ie hit Q to initiate) causes misclicks and errors where the similarity could be aiding in learning and switching. With a bit more consistency maybe we wouldn't need so much onetricking. Of course you can't just change; everyone works differently, but if the keys had similar arrangements it would at least help out a bit.
