Correct me if I'm Wrong, but Kassadin's W.
How was it considered a bug for his W not to apply to towers?
Riot-- you guys remember when you mini-reworked Kass, right? That was around the time you were removing basic attack enhancers from towers. (Mainly from AP champs).
So, why is this a bug? You removed it from the game so Kass couldn't push towers effectively. I'm fairly certain this was done a few patches after his mini rework.
I'm just confused on your clarity about fixing 'bugs'.
