I noticed a couple of times that there are very similar missions one of which has the win only and one of which doesn't in the 2 specific examples I know about
'Earn combat points for defending sectors' (10 tokens) the win only version requires 20K Points the other (Invincible) 25K ( leave aside this requires 100/125 KIlls where you have to be in a very specific area of the map)
'come in the top 5 of your team for x' Win only requires 3 completions other 5 so 3 mission is only better if you have >60% win rate
It seems to me (and i am probably as or more guilty than many) that this does not encourge best practice in trying to win?
I think that similar to WOT winning gives 65% bonus to xp and credits plus the times 2 for first win but to a degree this just happens and it doesn't make a huge difference if it is 55% OR 65% of the time, especially if you care more about tokens thant xp and credits.
