The roaming support wouldn't need any gold to be effective, because he'll be a utility machine. He doesn't need to do damage or be tanky, because he brings a lot to the team. Leona and Thresh come to mind. And yes the 3 would be at a disadvantage in XP, but at the most that would be a disadvantage of MAYBE 2 levels, and that might even be stretching it. 3 level 6's SHOULD beat 2 level 8's.
