User blog:Sentinel 101/Pro perks in Black Ops require more than just kills to unlock.

This MP Customization overview by GamesRadar reveals some info about Pro Perks in Black Ops; it seems Pro perks will require multiple challenges to be completed before they are unlocked, and not all of them are stricly related to getting kills. Only the three challenges for Lightweight were shown;


 * Escape Death: Escape death 5 times after being shot.
 * Melee: Unknown. Presumably for getting melee kills with Lightweight.
 * Offense Medal: Unknown.

So, what's your opinion on this? Like it? Or did you prefer the MW2 system?
