Wow, just checked out what 'Hobnobber' feat actually does, (other than having a stupid name). "You can attempt twice as many Gather Info checks per day during downtime."
Wow, what GM actually runs Gather Info exactly that prescriptive way? (unless you are going for a 4e 'skill contest' thing with "Make 4 successes at DC15, before 3 failures")
Wouldn't most GM's generally just say make a G.I. roll, to find out stuff? Or 'what do you want to know? 3 things? (where to find X, who X is, who're their friends) make 3 rolls....
It just seems pretty rules lawyer-y, to actually know you can make Cha# G.I. rolls to find stuff but with the feat you can make 2xCha rolls. Plus wouldn't that invite 2 times the number of potential failures. I know if a player said, "I made 4 checks but failed 2" I'd be more likely to put bad stuff than "I made 2 checks but failed 1". Especially if there's only a finite amount of info I could give out.
Personally, I'd much rather have a +2 to the roll, or say G.I. is bumped up a training level, or even (in 5e parlance) give it advantage....which seems to be the implication of the Feat text, but without thinking it through. Even then it'd be a weak feat.
