14:50 min, yes it is the kind of juggling. If you have wave or thorn you can 1 hit many creeps without killing them to wave them after/let them die cause of thorn. When you have immo and start to attack the creep you need to finish him and after you can change the target (when you control at lvl8 and other range lvls), otherwise when you need to kill them with second attack you waste more time than you would do it without changing targets. Im sure about it because long time ago i did the same thing at 1200+ bot, one guy reported me and i got 1 day ban for juggling. So be carefull from now because its not allowed to do.
