Actually there is a way to win like 99% of all fighting missions (including the hard ones).
You just need a stamina gear set for that.
Simply collect items with only stamina on it. They are easy to get since these items are common items and most likely you will find a stamina-only item in the sex shop after almost every shop refresh.
They really aren't hard to get, just make sure you have a stamina-only item for each slot.
(had, chest, belt, legs, shoes, necklace, ring, piercing)
Then just equip your 8 stamina-only items and take off your gadget. Now you should win almost every fighting mission (like 99%).
But keep on your missiles!
You may ask why and here is the reason to take off the gadget but to keep on your missiles:
Enemies in fighting mission are mirroring your stats and the dmg of the gadget (weak enemies have a little less and strong enemies have a little more of these mirrored stats/ gadget-dmg). But they are not mirroring the missiles, so the missiles are your big advantage over a fighting mission enemy.
Now just make sure to keep your stamina-gear always up to date by simply buying every stamina item that is better than your current one. It's pretty simple, since you will most likely find a stamina item in the sex shop after almost every daily free refresh.
This won't work very well if you are wearing only some stamina-items. If you want the full almost 100% winning guarantee you need a stamina-only item in every slot.
And on a side note:
This only works for the regular fighting missions. It won't work for the career fighting mission enemies since they have fixed stats.
Oh and be prepared to become a glory-victim for other players because with this stamina-only gear and without your gadget you will loose every duel.
But if you want to make sure to always (99%) get that special one fighting mission reward item this will help you a lot for the future.
And if you don't care about glory and you are hunting for max exp then doing hard fighting missions with this stamina gear is the best you can do.
In short:
An up to date stamina only item in every slot (without refinements ofc) + take off your gadget (but keep on your missiles) = 99% guarantee to win every regular fighting mission, even the hard ones.
It really works...just give it a try.
