Shyvana is unplayable, bearing a gameplay breaking bug. (date of bug occurrence 07/03/2016.)

The point of interest of the video: 0:07

This has happened in a game that had taken place two days ago. I had laughed this off as I was tired so I've without an issue assumed that it was a mistake of mine, I didn't even consider anything else(like a bug) to be the reason for that misplay. Anyways, if you're not familiar with the mode of smart-cast that I am using, here it is; All of the abilities' ranges are indicated upon pressing the ability's key (indenting it, but NOT releasing it). Only upon the abilities respective key being released is the ability itself activated. You can clearly see in the video that I had aimed as I had intended to aim by observing that the "Dragon's Descent" range was (last) indicated in the direction that I had intended for it to be executed, and that while it was aimed in that direction, the ranged indication had ceased being shown, meaning that that is when I had released (given the order to execute it) the abilities key. So yes, the bug with the dashing abilities of some champions that I remember was not such a short while ago supposedly fixed, is still somewhat present (somewhat because I've only obtained proof about it still being present with Shyvana, but there are many other champions who had this exact issue with their dash(ing) ability(abilities). E.G. Riven's "Valor" ability). Also, very important to point out, this has happened quite a few time since I've started playing Shyvana (that being some few days ago). Every time I've just blamed it on myself, but this here gives a better insight.

Side note: Wtf, have I used the possessive form of the word "ability" right..? xD
