well first off you need to be quick with the translocator when teleporting. The way you have your mouse setup will make it extremly difficult to get around with it.

My mouse is setup right click is my alturnate fire and left click is my main fire. middle mouse is for teamspeak. I use w-a-s-d- to move around and left shift is for crouching and space bar is for jumping.

The translocator: Left click fires the TL Disc and right click teleports you to that disc location. Now if you teleport too quick your weapons will switch to your rifle. Practise is the best way to get to figure out your best technique on how to get around.

Hope this helps alittle, If you need some more help just get on teamspeak and we'll help ya out.
