Kassadin is ridiculous
Whoever thought it was a good idea to let this champion out of Kalista tier needs to resign from the balance team.
This champion is absolutely unfair to play against, why is it a thing that a champion that deletes you as fast as Kassadin does is allowed to have nearly more than 2.5k HP.
Kassadin has absolutely 0 counterplay. This champion is just impossible to punish a tanky ass assassin with the strongest mobility in the game that deletes your backline by pressing R should not exist.
"Oh but he's useless before 6" Guess Kassadin deserves free elo for surviving until level 6.
There was a reason why this champion was kept in Kalista tier for all these years and that reason has not disappeared, gut him back into the hole he crawled from.
