Mid Lane Assassins falling short

From my experiences this preseason this patch was not an assassin revival of any sort when it comes to mid lane . Probably the best from the group super wonky huge hitbox on ulti now and has a weird terrible power trough at 2 items ramps back up at 3+ items . a hate it or love it rework I think they def gave her potential to be good but atm past 25mins her win rate plummets she has a terrible lategame and her cook time on passive needs to scale down to 1second as it is she gets hard countered by every adc lategame... removing the slow and nerfing some of the passive damage def helped kill tank ekko but leaves ap ekko in a wierd lack of slow hurts his early game trading I would lower the CD on his passive lockout back to 3 seconds now that its not a spam slow. a fun rework though his numbers definitely seem off should be able to proc his passive with his Q maybe increase the jump range a bit his teamfighting is pretty bad atm easily peeled kited and if he gets behind doesn't have much of a way to come back super item dependant. another fun well-done rework though her damage sometimes can be incredibly lacking mid/lategame I suggest speeding up the daggers at the very least if not buffing the scaling on her passive a bit.

Overall atm not much point picking any of them mid besides for something new and fun heavily out shined by current mids some nerfs to Ghost and exhaust could go a long way though hopefully 2.4 riot fixes some of them seeing as almost all of them mid are sub 50% win ratio with ekko being the highest.
