Im not saying hold off til you can perform a SC but if you have tp on 2 people and can do them it only speeds things up. I dont think i really ever say "hey dude you do tachi retsu and i will follow with shadowstich!" but i will try to time a WS i do to make a SC if possible. sometimes it can really speed up things. Also we dont usually change the WS we do just to make a SC just if they happen to make them.
