Future change ideas (a discussion)

Before I get started, if you're one of those people who down vote things without explaining what you disagree with please leave this is a constructive discussion.

The first thing to address Rework, redo, make as unplayable as possible This seems to be the idealogy that struck down Akali. I'm not against reworks, but if you change how something works in a rework don't remove the mechanic a dozen patches later. (Except Akali stealth that was kinda ridiculous). My main points being Irelia passive and Akali having any natural healing. New irelia was supposed to pop shields, but now she just auto attacks.... And Akali whose always had lane sustain now has to buy an item to sustain. That ideology shows less willingness to make something different and balance it rather than make something op and Nerf EVERYTHING about it. Like if kayle comes out really strong so they remove her invincibility, does that really count as fixing anything?

Item ideas 1- a mana item that goes for ad champions that doesn't waste gold efficiency on crit, sheen, or tear. Why? Well as it stands there is no really simple mana item for ad champions that don't ability then auto or spam 800 abilities to make tear worth while.

2-simple ap spell vamp. Why? Buying gunblade on an ap only champ isnt efficient, i'm not saying go crazy but like 5% spell vamp 200 mana and 90 ap doesn't seem horrible

3-more specific damage protections why? Void staff and % armor pen are great, but with crit changes again it feels like adcs don't even need to waste time on pen especially with conquerer changes making randuins feel like a mediocre investment

So those are some ideas, maybe not the best but that's why it's a discussion so please do leave a comment below on potential changes, modifications, etc
