Lucian, and passive bugs or intentional things?

So Lucian's passive I have a few issues with, and some could be intentional, if so I'd like maybe reasons as to why? then just a /shrug on my half I guess XD, and if not then I'd like to let you guys be aware of them.

1: Lucian's passive can be silenced?

• So yeah, picture Lucian dashing away from a Cho or Garen or into a Soraka puddle, He's silenced during the animation of casting E, and on his buff bar it states his next auto will be a double-shot. But nope only when the silence runs out.

2: You can flash his passive aa? and sometimes it deletes itself completely under some special conditions like losing vision, and Lucian shoots at thin air, also happens in lane against minions a lot btw, sometimes the game doesn't recognize the first auto is going to crit so you double shot a minion and deal like 1000 dmg to a caster then the second auto tries to hit the same minion? :/. -I can add some highlights of this happening if you'd like o.o

3: His passive doesn't allow to attack twice? -On this note his passive also doesn't stack Energized attacks faster and nor does . -Oh yeah and his passive doesn't count for either

4: This is more just me being super questionable? It takes like half a Lucian ult to kill an Aphelios turret. Also, Aphelios red Q is like a better Lucian ult, and unlike Lucian ult can't be silenced? huh? Like idm vs Aphelios as Lucian, I typically win that matchup in my games especially later on in the game, but these were some points I was also curious about :D
