Hmm are we only talking about the first clip with deagle?
We got rekt that and we wanted to get over with the game and we where just chatting alot, not caring about movement, position etc..
I mean, I run straight into palace without any serious crosshairplacement and peek without caring if I die or not.
Besides that, I have always done those little jumps followed up by sneaking or actually moving with little jumps, it often seemed to confuse enemies, thats why I tend to do it in spots where an enemy might here me.
Besides that, my movement was totally fine for my rank. When I was active I could do most important jumps, such as going from mirage window onto B short and ladderroom, the old jump on Nuke to get on the roof, some jumpboosts, like the one on cache B site where you jumpboost from site to heaven and so on.
Most people cant judge someone ranks based on a video and movement anyways. They always call everyone silver, because they think when they play they are so much better, but they arent :D
