Improving Varus; Listing Issues

I believe Varus deserves a buff. I will list several parts of his kit which appear problematic to me. Feel free to agrre or disagree. Later on I'll suggest tweaks in another post. At this point I'ld however like to gather feedback on his state. Do people want him buffed?

His issues:

• His passive is unreliable

• • It requires you to already be winning a teamfight to perform well, instead of helping you to get to that point
• • the bonus given is relatively low. Just compare it with Jinx passive's Q...

• His Q has a high potential damage, but it comes with a big announcment

• • possible AA attack is lost during the process of casting
• • it's worthless when uncharged

• His W requires him to land a spell to proc the damage

• • casting a spell actually lowers his DPS lategame due to the long activation time
• • Only Ap sclaing
• • doesn't benefit from Last Whisper and Arpen

• Casting his E often makes him fall back and be not able to reach / escape his enemy instead of helpinh him to do so

• His R only scales with AP, but no stat a carry would benefit from

• • It has a low travelling speed
• • It's only a root, meaning mages will still nuke and carries attack you

• he has no escapes
