While I agree that the other is stronger overall, it is necessary for me for one simple reason. If I am going for an Eye, I need to hit 2150 gold as quickly as I can without CSing (Sightstone, T2 Gold Item, Shoes, T3 Gold/SS Combo), and Bandit is a big part of this especially if I am able to AA poke well. 25 AA's is 75 gold (ranged), and that's not a hard number to hit given the number of fights that break out down there. In the first 5 minutes you should also get 50ish gold from passive minions, which ultimately shaves a minute or more off of getting those items early on, performance depending. Those little bits mean a lot when you're counting minutes and gold item charges.
Melee Supports benefit greatly from the 10g per AA, but as we all know, melee Supports are catching a hard shaft in this meta, so not a lot makes them feel better.
Outside of the Support Role, it doesn't hold enough usefulness (except for maybe a melee heavy top laner) to really be exploited heavily. If they buffed it, literally everybody would use it, because we all know how important gold is. That's why I feel that it's in a good place right now. For Supports, it's vital and necessary with their reliance on Gold Items. For everyone else, it's meh.
