I think when your first starting geting used to crucible I would try to have a kind of patient/aggressive kind of playstyle. By that I mean don't be so aggressive. For the most part since the radars always up people know when someone's coming for them. So it helps to be a bit more passive and patient and bait your opponent a bit instead of just rushing around the corner because you know he's there. I think it's helpful to think of it the way someone said to me the other day that it's kinda like being all crouching tiger/hidden dragon about it and waiting patiently and than quickly pouncing on opportunities that you see or that you can make. It's a ebb and flow of being slow and cautious and than explosive when it's the right moment. Hope that makes sense haha. Good luck man!
