Yeah pretty sure I saw someone CP sprinting today.
The patches never do crap for the cheats. I encountered one moments after downloading the latest patch.
On a side note, I'm having a lot of fun and success with the UMP recently.
Takes a little while to get used to (as it does with most wepaon and perk combos), but it's a beast of a lil' weapon.
Coupled with the loadout I have for it, it seems to steer me towards really forward and aggressive gameplay.
And finally, I don't know why, but recently I've been accused a lot of cheating by scrambler users. "How did you know I was there?!"

In general I think that perk has to be one of the most useless perks there is.
The only way it's any use is if virtually your entire team uses it... and even then.
