Lissandra Rework or Buff?

This may be long :) Over the course of the month I began focusing my time on mastering Lissandra . At first I thought she was really fun and I love playing her. Lissandra in my opinion has some of the best concepts for her character and kit. Her design is also one of my favorites, except her hair and face dont see proportionate to her body but its what it is, she has an intimidating presence with her high damage poke when its beginning to max, but when you start going a bit further into late laning phase when roaming is increasing, you find her usefulness and power to fade. I think the biggest issue with her is her design. They made a squishy engage mage with one escape which is gone when she does her engage leaving her a sitting duck if the combo doesn't pull off. Lissandra has great potential with her kit but having a squishy engage mage that starts team fights by getting in the middle of a team is a poor execution. Because in case her combo to engage ,E+E(blink)+W+Q+R, doesn't do enough, which in some cases it doesn't unless its pulled off at the right time with enough MP and AP, it leaves her in the enemy vulnerable unless you have which only prolongs your inevitable death. In my opinion I just think making her squishy was a poor choice, and It doesn't make much sense to have her surrounded by heavy black ice and all that armor around her and turn out to be very squishy. Which is where the poor design comes in. Its just misleading. You wouldnt expect malphine or garen to be squishy so having her look a bit tanky only to turn out to be as squishy as Veigar is just odd. Even with her high damage Q, her other abilities dont pull off that much damage to match. With her Q you can poke down an enemy very quickly with its low cool down and poke. But her W doesn't pull off that much damage, but I do understand it can root an entire team so that kind of, slightly, makes up for the lack of damage. Her E, to me is the weakest link. Yes it is a blink ability and saves her from ganks, I will say Lissandra is pretty much ungankable and I do love that about her kit, but it also doesn't do the damage you would expect coming from a big claw running at you, even in late game it doesn't pack the punch her Q does. Her E (I heard is being slightly changed in regard to the speed, but she hasn't had the rework so ill speak in present) is really slow and practically easy to dodge if your behind minions and see it coming. It is useful, however for wave clear late game but thats the only pro aside from a blink. Her R, her whole being, is also lacking something. The damage output of her big AOE eye grabbing ult doesn't do much damage like other ults in the game. Especially early-mid game, her R is really just either a , or a single primary target CC. Yes, late game it does good damage, but thats only when you have 500+ AP. But when you get it early on its usefulness is very limited and not so much help in roaming ganks and early team fights as it doesn't do a lot of damage for an Ult like: . Her R, despite being big and attention grabbing, isn't much to worry about for a team or a single person unless you have 1/3 HP with a team chasing because all you have to do especially in a 1 v 1 is wait for it to be over, assuming you have enough HP to continue to fight. Now that you read this far, sorry, I want to describe a possible mini rework, despite my knowledge of the alleged upcoming rework just for the fun of it.

Passive- Have black ice corrupt areas shes in contact with when she stays in the area for # of seconds and have it "melt" when shes left the area for # of seconds. Abilities and CC and empowered in this area.

Q- Keep basis of it. Add a 5% more slow. W- Just ever so slightly expand the radius of the aoe and boost the AP% or base damage E- Make claw more faster with higher damage R- Keep as is, but when casted on corrupt black ice the damage is greater and Lissandra emerges with higher decaying or in her case melting black ice armor for 2.5-3.5 seconds. So she is able to leave a team fight and not be so squishy coming out. Please comment on my ideas, they just ideas and would like some feed back and thank you for reading my long ass post. Also ingore any errors, english isnt my first.
