No it's not. If you're going to feed then choose just one of your other teammates to feed till he/she doesn't need any more resources from you then move on to your next teammate.

Mr Con:

I was just wondering if having forge feed two players in 3v3 is ever a good tactic.

I never thought it was until a recent UA 3v3, we had a forge tribute to my anders and a cutter the entire match and it seemed to make the match a lot easier, it was a lot easier to switch to gremlin counter and pump out units and i feel if forge had boomed canister or massed flamers/marines then it would have been more difficult or we would have lost. Does this ever happen in high level arranged 3v3?

Note: The forge very slowly built and teched grenadier hogs and I was about rank 80 3v3 UA at the time so it was relatively good players.
