Minor graves flaw for Co-op vs AI
 

Soraka will still cast her ult to save low teammates while she is smoke screened. She has no way of telling if her teammates are low HP or not while in it. Bots obviously aren't hard, but it takes away from the "Realistic" feel when trying to practice a new champion.

Looking at the left side of the screen where char. portraits are helps you know...

And it's BOTS.
