While I've really enjoyed the free roam sections of the game, there are still a couple of things that I really don't like, and so do plenty of other players as I believe.

Whenever I accept a bounty mission for a free roam session, I always start out at the very starting point of the free roam environment, even with other players in the progress of said bounty mission, regardless of how far away the rest of the team is. This is pretty upsetting since I begin so far away from the rest of the team in the action of the mission, which is really not a good thing for the cooperative spirit of Warframe since the sections of the missions I try to participate in become completed before I can even catch up to everyone else, thus effectively excluding me from making contributions to teamwork. Not only that, I also don't get to opt of automatically joining other teams in progress when I enter free roam. There should be an toggleable option to opt out of joining the free roam sessions of other teams currently in progress, and if we do automatically join others in progress while on a bounty mission, we should instantly transported around the spot of the closest player to the mission's current objective distance-wise.

Whenever I fail on a free roam session because I die and have no continues remaining, I lose all the stuff I earned except for rewards from bounty missions. This is a seriously frustrating thing, since all the work I did to gain said resources (except bounty rewards) gets wasted and is now for naught. We should be allowed to retain all the resources we earn on free roam sessions, even if we die without any more chances to revive ourselves and thus fail.
