As everyone knows now CB and now also ''Europe'' changed yawspeed from 140 to 0. But why is that?

cl_yawspeed EQ 0

What does it do? Yawspeed determines the speed of the turn-movement. A 200 yawspeed player will turn slightly faster with arrows then a 180 yawspeed player. 0 Yawspeed reduced the turning speed to zero a.k. players can't move with arrows.

All games like cod/cod2/quake allow yawspeed between 0-200, but ET just changed it.
