@RiotRepetoir: What would you think about Lissandras Ultimate in the current State of the game?

Lissandra was release a a few years ago, before Riot became comfortable with allowing teammates to stasis other teammates. With this new concept running around more and more nowadays(Looking at you, ), How would you feel about allowing her to "freeze" her teammates to save them from a large burst or DOT effect, maybe apply the heal from the PBE as well.

Thoughts?
