So you buff Fizz when he doesn't need it, but you haven't touched Kassadin?

Kassadin is a super hit or miss champ.

He either hits: Gets a little advantage and completely destroys.

Or he gets dumstered on and cannot come back from where he is; Unless he last hits everyone in a teamfight. But to do that you need to be carried by your team.

Kassadin, even if he is not hit or miss, is very easily countered. By a lot of champs, and also by not letting him have any farm until 6.

He goes in with his ulti and Q's a target and then W>E then is left completely vulnerable to CC or being bursted down before your CDs come back up. You can buy a Hourglass but that will only let you live a few more seconds most of the time. You go in with your combo, then use Zhonya's Hourglass, and when you are out you will be CC so you cannot ult away. Kassadin's ult has a cast time and you can be CC'd in that time and it will negate your ulti.

I don't get why Riot is buffing Fizz but Kassadin. (and Urgot. Rip)

Why?
