Sivir/Anivia
As i was playing Sivir the other day I faced an Anivia support. My thoughts were "haha I can counter you and get sustain." But when I used my e as Sivir and Anivia would go to stun me I would still get hurt and stunned but gain mana back. I would go up to her trying to proc her stun and would get killed in the process even though i used Sivir's e correctly. This only occurred with her stun. Her spike would still get blocked like normal. Please post comments of your opinion.
