User blog comment:Rakanishu2199/Toggle on Sunfire Cape ?/@comment-12136762-20130907205820

Agree 100%, a small change that would be extremely convinient for sunfire cape users. Wonder why Riot never thought of this. Cho'gath can toggle his E for similiar reasons, so if Riot were informed about this excellent suggestion there would be a great chance this would become real.

While we're at it, Abyssal Scepter also have a bit of the same problem (if your opponent sees that debuff icon, while you're sneaking up on him/her that is), though it's a minor problem in comparesion to SfC.
