Without the sharingan
He can still use raikiri
He actually has more access to his 1000 jutsu now
He now has slower reaction, increased stamina and physical capacity, no kamui, and more access to jutsu. He is no way fodder and still kage level.
Ps.He has some access to gates
He can still use raikiri
The sharingan was needed for raikiri before because it required that one move at a speed that causes tunnel vision, the sharingan perfected it by allowing fluid movement for counters and precision. This became obsolete when Kakashi learnt how to use raikiri with a kunai that he can simply throw or keep in his hand
We can view the sharingan as gravity training in a way for chakra. To cope with the chakra taxing attribute of the sharingan kakashi developed excellent chakra control as evidenced by his increased stamina throughout the series and his performance in war where he could dance with bijuus ffs (partially transformed but impressive cause 4 tailed naruto had everybody shitting their pants ). Now that his sharingan is gone he has way more stamina. You don't forget the jutsu sharingan teaches you either or base sasuke wouldn't be able to use his chidori variants or lees taijutsu
Ps.He has some access to gates
