I can empathize with the trophy collectors, being one myself. It's quite frustrating to input the amount of time into a multiplayer you probably wouldn't replay. Multiplayer trophies especially frustrate me, knowing I would probably never touch them, anyways, but they definitely are the only obstacle left for the platinum. It's a hobby, like one does to collect bottle caps, cards, games, etc. One doesn't necessarily have to enjoy the game but the fact of collecting is sheer satisfaction of an accomplishment enough. With that said, I'd actually would boost other multiplayers that take too much effort for the amount I'd be willing to invest in them. I actually enjoy Bioshock, so I don't require the need to boost. But, Assassin's Creed Brotherhood, I will most likely boost. I just don't find it as enjoyable.
