Kog Maw is unhealthy + Lulu W bug/Silence not working at times

After playing a game against a Kog Maw going full attack speed, I feel like he is really REALLY unhealthy, like Yasuo unhealthy. We all know Kog Maw as that one adc who can be a pain in the jungle, because he is, he can go anywhere and be cancer, his attack speed when he uses his W is really annoying, it should deal less damage than it should especially since he has his Q to lower the target's armor/mag res (one of them).

Also when I used my W (the one that turns people into squirrels and is supposed to not make them use any ability or what not), the Kog Maw kept attacking me like if he was still in his original form, so I died... There is also a problem with silences, sometimes (like 1/2 times) some champions can still use their abilities while silenced.

I am not being salty or whatever, I am just giving feedback and also telling more about some bugs Riot left out.
