Mastermind Rogue can grant advantage at will and I've seen them in play.
To a creature w/in 30’. So not likely to be appropriate at long range for archers, unless the Mastermind is being a spotter for the shot. Not impossible, but it will be a situational option.
Same for a 5 person party with an Archer Fighter, 3 Spellcasters and a Mastermind Rogue all “super buffing” the archer. Not impossible but the limiting factor is getting the group to play along, again situational.
Works in a CRPG game, but many players do not want their character to be the Fluffer in Chief
