I was grinding some Prots yesterday, after about 150Ped TT ammo my skill boost kicked in, lasted all of 5 mins, saw a few extra green lines, nothing to see here, move along....
my highest or most favorable was blp 200% for 12mins, fastest 12mins of my hunting career think i slaughtered every trooper and legionnaire on the map ...and yes the skill gain was very very noticeable
