well you could try to predict where he is going to run and tele ahead of him and shift smite. becuas if you have a R3 weapon your range isnt too bad and while shift charging he always goes in a straight line. it is alot harded to actually predict where he will be going charge because we all know that blck is a good pker so he will make up some complicated paterns also i believe that the shift charging is kinda like wwing as far as how far you will charge so he could short charge or long charge. is he long charges then he will have to go in a straight line for a longer distance.
