LFG or finding friends is the most efficient option in general if you want to avoid any blue berries and their antics of any form otherwise you are at the mercy of matchmaking. Personally, those AFKers don't bother me since I no longer have any business with forges and at the very least it sends Bungie a message that this form of grinding is no fun.

Literally, the most efficient option is just the regular matchmaking. Even a low-skill blueberry or a new player is capable of handling the forges, as long as everyone's actually make an effort. Like, even being "at the mercy of matchmaking" would not be an issue if people weren't cheesing the system.
