Quality of life changes! (Ideas)

I've been thinking about some QoL's enhancements that really need to be implemented to the game:

Jax R's passive: something to know on which AA you are on. (Sometimes I think I'm in the 3rd hit and the buff is either already gone or I'm actually on other hit, and I just feel like count dracula (from sesame street) every game: "one auto-attack, two auto-attacks, THREE auto-attacks (,u,)").

Cassiopeia & Karthus Q: it should show the range of the ability, so that people can get used to the range. (Not knowing the exact range makes it harder to use than they already are.).

Ziggs W: ability to self cast. (Would really help when trying to run so that you can just alt+w and automatically press w again.).

Ranged champions: an option to always show own attack range (similar to rapid firecannon), playing Kog'maw, Tristana and Jinx is very confusing at times. (Twitch already has this on his R so pls rito). I really think it would help lower elo's adcs kite and position while not affecting higher ones.

Alistar combo: pressing W and holding Q afterwards should "queue" the Q to do the headbutt pulverize combo, I always have felt that it has a weird timing and I don't think that it would affect his power in any way.

Cassiopeia: some clearer way to see which enemy is poisoned, the current icon for poison is miniscule (could be some sort of Rengar-esque view (his ultimate) but green.

That's all I can think for now. Thanks a lot for reading!
