Edit: this question is answered. I must have just blacked out my memory of how riposte spell worked before update
"I can remember that standard attacks by switching tiles was reflected by riposte before the update. I just played against Elena and was very surprised when a combo of tiles killed all my heroes.
I can’t find anything about this in release notes.
Together with the hidden change to dispel it this update has been a huge stealth buff to riposte. Am I right?"
