Cassiopeia rework, I was wrong!
I said she is not much fun anymore, I was wrong she is still loads of fun. Yesterday I played 13 games with her, and today I couldn't wait to get home to play her again.
I carried most of the games so hard with the new Cassio, I think once her Q range gets reverted she will be at least as strong as the previous Cassio, if not stronger.
However I have to say that she does not feel quite the same anymore, still retained perhaps 60% of her playstyle feeling but I think it would have been better if you left the old Cassio and created this as a new champion! Now Riot basically removed a unique champion from the game and replaced her with another unique one instead of having 2 champions. If we had 2 champions instead, no one would suffer a feeling of loss.
So I really like the new Cassio but what bugs me is the farming:
CSing with the new Cassio is either a pain in the butt or quite mana intensive.
My suggestion would be to increase the base damage on her E when the enemy is not poisoned and subtract it from the poison damage, that way the last hitting with her E will not be such a pain anymore, especially in mid and late game.
I don't know if this new Cassio is as fun as the old one to me, time will tell.
