Idea's to improve Lissandra

Improve Lissandra's Passive and her Ult

1. I don't think Lissandra's passive is bad at all, it conserves mana early game to poke the enemy champ with ice shards. HOWEVER, it does need a bit of a buff. For example, "the number of enemies hit also reduces the cool down of her abilities" something like that would make he a lot more viable since she doesn't do much damage. Although something like this can make her OP, so raising mana costs on her various abilities would be a good idea to balance her out AND encourage the use of her passive.

2. Lissandra's ult is almost useless. It can be used as a glorified zhonyas that slows surrounding enemies or as a burst technique for locking down opponents. This is pretty good by itself. HOWEVER! Why the heck do champs like Morgana have a stun that's so much longer than her ult? The stun on an ult should at least 1.5 times as long compared to a normal stun ability. In addition, it does almost no damage unless combined with her other abilities, which burns mana btw, and it isn't instant so champs like Katarina can kill you just after you hit ult to save yourself.
