Lissandra's Frozen Tomb Prioritization
Lissandra's ult seems to prioritize herself, IIRC and from experience. I think that it would make more sense to prioritize enemy champions.
I was in a situation where I was running from a Master Yi. After he alpha striked me, I tried to ult him, but ended up ulting myself. Because of that, his team caught up to me and managed to kill me.
We already have an option to self cast (ALT + R I believe), so if I wanted to ult myself, I would've done that and not tried to target Master Yi. It just makes sense cuz in the case of an enemy champion being on top of you, you're likely to ult yourself even when your intent was to use it on the enemy.
Just a thought.
