Why sightstone won't get good upgrades
This why we can't have nice things:
:(
so to fix, lee sin cannot dash to wards for two reasons, 1st hes blind and wards don't make any noise so thus he can't find them; 2nd we want decent upgrades for sightstone so go away lee sin. Lee sin can still dash with safe guard to allied minons because they make noise, and smell... Blindness is no impairment to a smelly enemy -Lee Sin joke
next add new ward ideas: a health regen sightstonefor those tanks and sorakas out there, and a sightstone for those who want more magic damage, maybe an AD totem so maybe it becomes viable, properly for other players not just cause it makes certain "ahem"
champions really op. other ward ideas: scavanger - sightstone that gives you free ward charge when you destroy an enemy one, stalker - standing still makes you invisible to true sight and CV after 5 seconds.
Also about this  guy, should rework kit so blindness and maybe smell are actually part of his kit, and make it so its actually hard to see like something akin to  's burrow effect, you have the technology you've said, so why not, in his current state hes broken in the sense that no amount of buffs or nerfs will fix him in a way that makes him less of an issue.
This came to mind after a fun game as a support and finding myself hating that I NEED sightstone but its upgrade really stinks unless you're a tank, even then. Thoughts? comments?
