Grave's passive should be interuptable.
As a
suppoert, i wait for so long he used all his bullet then outrageous him by my stunning gems.
And i realized that all i do is give him time so he can reload hit shells while stunning by me...
Why? If you planning him to reload his shell, why he can still auto attack like normal? Every single times i see he out of shells, i think it the time for me to go all in on him and, wow, he reload the shell before i realize im already died by 2 hit from him.
All i see from the passive you give him is :
GRAVE deal damage in auto attack equal to 175%AD at lv 1 up to 470%AD at level 18. 470%AD. haha... 470%AD.
usually get 100% crits so easy right now. He also get 40~45 CDR by that far.
Plus, he have 2 Shells. + 1 shell on his E.
