Sacrificing a damage or mobility spell just so that you can have a chance to farm against manaless spell spamming champions like Yasuo, Zed, Riven, who will all pick a damage spell is not a fix. Being forced to take a useless summoner spell or use the mana regen in the utility tree because riot wants to get rid of mana pots is not a fix. It's a nerf.
