Having to land on the same station to get a mission it's way less than optimal, that's for granted. Now, you don't always get the same missions nor the same rewards for the same mission (yeah, I know. But I have been paid roughly 30-40% more than my mate just because more than once).
So I saw this thread and I'm surprised not that many people seem interested, yet it's still one of the main things I think FD should focus on, to take the Wings feature to the enjoyable level. I'll expose some situations first and then I'll input my suggestions.
1. You can get an assasination mission that's around 300k-400k. Target: DANGEROUS Anaconda. So you want to do this mission with your mate, which should be easy-peasy - but he/she cannot get the mission since it's only for Allies of that minor faction. He helps you out, his final profit being -22.000 (since he ends up killing some Innocent NPC that had nothing to do with him).
2. You find some juicy "KILL 40 CIVILIANS IN 2 DAYS" sort of mission. You need the money, yet your ship is SO not meant to this kind of mission, and you can't afford something better. Luckily, you've got this wonderful friend from situation 1, who made some money after paying that awful fine he got ('cause of your poorly mission-picking parameters) and got himself a very nice Vulture. So you can rock this thing together like pro's... except he's not online yet. He ends up helping you (again), since he's a nice lad, but there's no profit in that for him (again. Plus he might be losing REP like crazy).
3. Well, there it is! The Assasination mission you guys have been looking for. Some big fat Conda in a wing, with a handsome reward. What could go wrong. So you take your Cobra, and call your Vulture friend to tell him to stop whatever he's doing, get online, travel from wherever he is to wherever you are and accept the mission (note the amount of time spent in the process, and how your gameplay would basially be... doing nothing, really). You find the target, you start all the pew-pew business. Now, you're shields melt like butter against those badass lasers, and you step back a little whilst your dear friend tanks the beast for as long as he can. The process repeats for some 10 minutes, and the situation is: YAY! Conda's shields down, Hull 3%!! VICTORY!! But... Your mate has died in the process. You end up killing the Conda, yup, but your friend not only has to pay for his ship, but gets nothing from the mission (but a nice REP loss, surely).
Now, how would improving the Wings system (by adding a SHARE button) help prevent those situations?
Situation nº 0 (remember: your friend might not be able to accept the mission!!) would imply that missions are offered to individual pilots, and pilots choose to fly solo or to "hire" a wing. Keep this concept in mind, since it's most useful for situation nº 3.
What would this mean? That you're free to hire a wingman who's not necesarily allied to the minor faction offering the job - yet, he's technically going to help you out, so they'll have to accept that as it is and pay part of the reward to this guy.
Obviously, the share button would make your wingman an active part of the mission you decide to share (or vice versa), therefore meaning he'll get a real reward - apart from the satisfaction of helping you out - for doing stuff that does actually imply a loss (the REP loss I mentioned earlier, for example). Now, about those "2 DAY LONG" missions - hurray! You could SHARE your mission as long as your friend is online and in wing, right? So problem solved.
Now, assuming that there's a SHARE button, and that jobs are assigned to individuals by minor factions and those individual pilots share their missions with wingmates, they should be able to choose precentages when it comes to implication and risk in the mission. One could easily kill 30 out of 32 pirates in a mercenary mission while his mate is killing 2, and a 50/50 split looks not entirely fair, does it?
So, yeah, here it goes - you get online, your friend is already on Elite. Sends a wing invite, now you're in wing and you get a private notification saying "CMDR Friendly SHARES 'An Example Job' + mission description + total reward + amount offered for job completion || Acept\Decline".
Please note that even though bounty hunting seems to work fine with the actual Wings system, we still need to take care of Pirate-mission players, Smugglin-mission players, Assasination-mission players, etc. To be honest, I have no idea how hard this could be to impliment to the game - but no doubt it'd be one of the most awesome things that could possibly be done as it is today.
EDIT: Plus, of course, missions actually and exclusively meant for wings - that's an absolute yes, isn't it?
