While you are at checking wing missions, please check the Massacre Thargoids ones please.
Because 3.7 ish millions for killing a basilik is not even a joke but a troll.
3.7M for something that's a risky fight even in an A-rated conda, with ten times that in rebuy if you lose.
Honestly, for the dangerous stuff, this rough formula should apply:
(probability of ship destruction) * (cost of rebuy) = where you start for reward values. Hell, make that the formula for rank.
Elite-ranked combat mission? Multiply chance of this mission's opponent taking out a corvette by the rebuy of an a-rated corvette. Then add some gravy on top to make it worth doing over a zero-risk mission. sure, you can reduce your odds of getting blown up if you've got a better ship than the rank expects, but your rebuy will be bigger too, so hopefully it'll work out. Conversely, if you think you're good enough to punch up - well. They expect 50% chance of a rebuy on a FDL and you're only in a vulture? Godspeed you crazy sonofagun.
Mission based on exploration rank? Well, not so much chance of destruction in combat unless it's specifically a risky thing, but you might splat into a star at some point if you nod off partway along a 20kly journey, so take some (probably pretty small) chance per kly and multiply it by the cost of the ship someone that rank might reasonably be expected to be exploring in - dbx, asp, jumpaconda, whatever.
