Cassiopeia cannot kill anymore early lvls
like you throw Three Es and you are oom and you just have done half the health of your opponent, her mana pool translates into soooo litlle damage, if another mage downloads their whole manapool into a champ they are probably more than dead. I find it unfair cuz then enemies can just pot their health up and you are just one sitting duck in lane gettin abused by your opponent.
