Lissandra passive update?

I read on surrender at 20 that there is a possible update for lissandra passive. I really enjoy playing her and i agree this is needed. Here is my 2 cents on it:

I feel liss is being played more as a bruiser and her passive refelects more of a ranged caster. Well its hard to be a ranged vaster when her skills are short ranged. Ie roa and similar bruiser idtems are idea.

My thought could be the following: i initially had the idea of blood thirsters over heal, but based on mana. So something like when he regens mana the gets a form of shield. Only problem is the only time she would gain a shield is right when she leaves base.

Then i kept thinking. Liss tends to spam skills. So if there was a way to make it where she has a chaining passive. Ie lets say she slows an enemy she gan gain a sheild or a termp mana boost. If either of them are depleted then the opposite is activated. So she uses the temp mana she gets a shield. Or her shirld is depleted and the gets a mana boost. This makes it so she is rewarded for staying in the fight.

Only thing is it would feel like kassaDin.

There is however the full burst shotgun approach. Which i really dont think the mana part is a problem. I think the only real benifit would be for laning. i think a movement buff after using a skill would make sense with her glaical path but the has rnough slows to balance that.

I think an extra magic pen would be very nice for her But it could easily be very unbalanced. If it was a stacked magic pen where if she chained skills would be nice but her cooldowns are too high for that imo.

I love too play her support, and with that i would like to see her more usable in more roles. Its hard to pin point a good upgrade for her, but i hope reading this slarked some ideas.

I would love to hear some other ideas, or reasons why you think her passive should stay how it is.

Thanks guys!
