My friend who taught me how to mid would use her alot against me(his main) I was always Swain(my main)
Anyway after countless 1v1's of him blowing me up, he finally told me how to deal with her. Here's the secret....don't die.
Her scaling is so awful late game that even when fed in our 1v1's, late game he struggled to kill me as Swain. As long as you don't feed, she will be worthless later on. The biggest tip I can give you is to recall to base if you need to. Being at 25% health trying to protect your tower in early lane phase will result in her diving you, killing you, and blinking back to safety. --- Boom Goes the Dynamite!
