Forum:+2 to Find Rare Items Viable or Not

Ok so, I've recently noticed on mods and been informed about +2 Team Find Rare Items,  is this something I should be using? Will it effectively increase my chances of a pearlescent? I believe the typical number of kills it takes to get a pearlescent is something like 62. Will this class mod effectively reduce the number of kills? Math would be great if anyone has the numbers.
