because I think that if your team leader is resting (sitting down or lying down), the whole team benefits from the hp/so recovery, even if some team members are not sitting down... I think this is true, for some random reason, maybe someone can confirm it?

I'm pretty sure the whole team does benefit if the leader, and only the leader sits.(Meaning the leader for sure sitting, anyone else don't count) Also, if you are in a team, the regular sitting recovery doubles for the 5 seconds, now 12 hp and 6 sp.
