I didn't mean it in that context Ryknick. There's hardly any teamwork in Solo Fortress 3.
Sandvich is one of the few good unlocks, I agree.
Buff Banner is, again, situational. A good soldier always keeps his shotgun handy on certain maps, while others are better suited but not tailored for the BB. It is purely situational.
Flaregun is useless, that's been explained in my upper paragraph.
Engie unlock has yet to be tested or shown anyway in game, I highly doubt the engineer will be worried with helping his team when he has his wonderful crits to score himself kills.
On another note, there is very low teamwork on TF2. I have never seen a heavy drop a sandvich for anyone before. And the soldiers use their buff banner at the stupidest of times so they can get revenge or save their butts from dying alone. I have never seen a pyro use the flaregun to help a ranged friendly, only to spam them at the snipers on the battlements or down the sewers.
Sure, there are people who use them properly but the majority of TF2 is focused on netting kills and/or getting revenge.
Oh, and good luck helping your team while you're dead because you ran out of rockets/caught off guard wielding the flaregun.
