[GAMEPLAY] Lissandra's ult is delayed after casting.

I have played a lot of Lissandra lately and have seen this issue many times. The issue is with her ult not going off quick enough. For example, if an enemy champion is within range of her ult and she ults on that champ, the ult works so slow, that the enemy champ can move out of the range and not get hit with it.

The slowness of the ability also can affect team fights in other ways as well. Last game, I was playing against a Yi and Yi was auto attacking my jungler (shaco) so I came into the fight and ult'ed on Yi. The animation started and the circle on the ground was there but after I started the ult, Yi used alpha strike and he was bouncing around striking us. After alpha strike was over, the screen showed Yi briefly encased in ice from the ult (pretty sure the ice stun time included the alpha strike time). Yi isn't the only champ in the last two days that this has happened with either, I just forgot who the other champ was and what movement/attack they did.

I have also seen an issue with the ult working on Lissandra too. After you press the ult, there is a brief delay before she is encased, during this time I have died multiple times.

Unfortunately I don't have recording software on my computer to show the yi incident and it is tough to show the brief delay with just screen shot recording anyway. Items seem to have no effect on this, and this issue occurs on both Twisted Treeline and Summoners Rift.

I noticed this issue started occurring after the slight Lissandra re-work. The old ult used to go off faster. I'm not sure if the delay was programmed into her re-work, but I don't think other champs should be able to move or attack after the ult started on them. Could you please look into this issue and respond? Thank you.
