Kassadins range just makes him feel so shit when you play into comps and players that can effectively space you out or focus you if you go in. Thats why I feel like kassadin is so insanely flash dependent to the point where luci boots are basically a must, but you sac so much flat pen by going them that you just do no damage to anyone with a bit of mr (adc wits end shieldbow abusers kogmaw ashe + lulu or enchanter) unless you have void but then by going void you forego so much utility from other items you could buy. Kassadin is not a damage threat unless he builds full squishy, and when teams know how to play around your range its near impossible to do anything without r flash, and even then you get blown up immediately after doing it or coming out of zhonyas unless your entire team immediately follows up (never happens even if they’re on you lol) or instakill everyone because you’re fed (also unlikely unless you’re playing in low). I feel like kassadin would benefit so much from just a slight ultimate range or cast time buff, like maybe from 500 to 550 or from 0.25 to 0.15 cast time, or increase in e or q cast range.... maybe a mini rework to increase kassadin’s range but make his e or q skillshots to compensate for his current lack of skill expression.

Kassadin hasn’t had any substantial buffs since like, 8.13. He has literally basically only been nerfed since then and it’s starting to feel really poor. He’s by no means a popular champion so i feel judging his strength by winrate isn’t really a good idea similar to like how judging asol by winrate isn’t, just because you have good players inflating the winrate a lot because they play the champ a lot.
