Game Mechanics: Rog hide pulling, blatant exploit that needs to be fixed

[Calabee]

i've seen many threads regarding ''invis'' pulling, but none talking about the biggest exploiters of all right now? Circlet of shadows / pulling while someone cast invis on you is legit, pulling with sneak / hide WHILE you are midcast (you need to bring up the ability bar) is definitly an exploit and should be fixed, you aren't allowed to use abilities mid-cast, period.
