you dont have to fly around all the tih ame with sentinel,yoou can just sj and block sometimes…although it wont get you TOO far with a good cable on your ass. the reason you see sentinel flying in videos is cause that is his most mobile state.
nobody really knows how long unnfly actually lasts…its pretty random n can’t put an exact number on it
people shouldn’t forget about sentinels j.lk, j.rh as a pretty quick overhead! although i wouldn’t recommend this on cable unless you just willing to take that risk to get that hit =) it can lead to half life =0
