I tend to send people spare weapons that will do the job better if they seem to be held back
I have a few spare items banked I would never personally use (polaron for example im not jem hadar so I regard them as not any use)
That's a interesting thing to do - there are certain non [borg] weapons that can potentially do impressive damage in the right hands, or allow the team to do attacks that the AI cannot react to.
Spare pulsewaves, sniper rifles and a compression pistol or two might be worthwhile to give out in case you see a team with DPS or control issues. My tactical toon somehow dishes out immense damage with her tetryon compression pistol.
Believe it or not when ill prepared players get a hard time at elite grounds some of them adopt a stubborn mentality and will just fight it out to the bitter end, while veterans just ragequit and leave.
