So I know some of the Kassadin fans are still in their phase and questioning rito on their ideas of "balance." Many believe that the nerf to 450 range was waaaaaaay to harsh as rito noticed, but what about the more recent "buff" to him? Is it actually enough to bring him back to a reasonable champion, or is Riftcrawl still too disappointing? I'm not a 3 year veteran or anything like that, I've only been playing the game for about 5 months, but I have watched many a pro's games along with playing myself so I have a DECENT understanding of the game.

Here is what I propose:

For Kassadin to still be able to make those super long leaps would be great. I agree with rito about 700 being way too much. But I think 500 may still be too short. My idea is increase range to 550-600, but add a small cast time such as 0.25-0.5 seconds or after a certain number of casts like 2-3 add the cast time to imply "BRO IM GETTIN TIRED OF ALL THE HOPPIN AROUND!!!" and change mana cost and cooldown to adjust further. Just my two cents on the issue and I would love to hear what others think of this! "The balance of power must be preserved!"
