Lissandra Update/Rework suggestion

So as an avid Lissandra player in 2012-2016, I have seen her go from a free zhonyas and a free skill to a free healing zhonyas and zombie ice clones that chase and slow the enemy. As of the introduction of new champions and updates, her skill set is particularly niche and safe pick choice. For an all-in control mage she gets her ult, and zhonyas and then boom dead. The skilled Lissandra mains might have time to channel an ice claw for escape if the team fight/engage goes well for her team. Otherwise she is cannon fodder.

My update/rework suggestion lies in relation with the other Iceborn Avatars, Ashe and Sejuani. Respectively, they have skills or passives that allow them a stacking mechanic that applies something relative to Freljordian lore. Ashe with her focus stacks that grant her a flurry of arrows - alluding to a blizzard since her skills slow. Sejuani with her 4 melee stacks that allow her to freeze her opponent for 1.5-2 seconds (guesstimating).

For Lissandra, I suggest an additional passive tied to her ult. That passive being a stack based slow to CD affect. What I’m suggesting is a new mechanic that affects the CDs of other players rather than the mechanic like Malphite and Nasus - slowing auto attack speed.

After level 6 and ranking up her R, her skills will be “enhanced” by the Watchers, applying stacks (up to 3). Each stack will apply a stacking slow of 10%, at the final stack it would apply Hypothermia and increase the CD or place on CD all skills for 1/2/3 seconds at levels 6/11/16. This passive would go on a 20 second cd after proccing on individual champions (similar to Udyr stun/Sejuani stun) as to not lock out an opposing player from their skills but still create a tactical re-evaluation of every situation against Lissandra.

As of right now her Q, applies a slow, the suggested rework would remove that. She would have no slows prior to lvl 6, but she would have her root from W (Ring of Frost) and her escape tool, E (Ice Claw). She would still maintain her current passive with the ice clones, after lvl six they would apply one stack after its explosion. Her R would apply max stacks on target opponent and uniquely, lower the cd of her non-Ult skills the same if she targets herself. The heal on her Ult would be either removed or cut in half for balance.

Ultimately (pun intended), she would bring a new yet lore filled mechanic to her kit and to the game.
