Why did he use the box? LOL
Let me see... I'm playing dust2 at bombsite A, I don't have any teammates at catwalk, and I'm being flashed from long... so... from where should I check catwalk without being shooted from long.... hmmm, hard decision. Oh wait... a box!
And later on, my teammates just arrive from spawn and start spamming long. I don't see anyone catwalk after all the spam.... should I check long from this box, totally protected from enemy fire, since they are distracted by my teammates?
He barely moves from that spot, how can you say he is aim-locking if he cleary knows that there are 2/3 enemies at long? He was just preparing the shots, of course he moves his moves towards long while trying to cover himself behind the box. Basic play, the jump shot is just a random shot.
