I learned to move on Oz, then moved to TFC and used the HW Guy. Was hilarious watching people approach you from the front, as you run around them in a strafing circle bunny hopping until they just drop from the damage...
...I played HL2, and CS:Source for about a year then stopped when DoD and TFC2 didnt come out right away...Still waiting on them both. Now its all about WoW.
