You don’t get any XP for winning in ETQW. What happens is all defenders get XP for completing a defend the objective mission. You know, defend the objective for 4 minutes, get 10 XP. What happens is when you win as defender it gives you the XP for completing this mission. So people think they get XP for winning the map, but they don’t. Winners get nothing, defenders get a mission completion XP award (so in effect they do get an award for winning, but again it’s only the defenders).
BTW, this is one of those things that really skews the XP awards heavily towards a strong defnding team. If you full hold the first objective everyone on the team gets and extra 60XP
10 for the first 4 minutes
20 more after 8 more minutes (clock is now at 12 minutes)
30 more when the map ends (clock at 20 minutes)
Total 60, even if you did nothing for your team.
BTW, the XP goes to your class category, so if you are planning to play a different class the next map what you do is switch right before the map ends and you will start the next map with the first unlock for your class. Also makes it harder for attackers to get the medals for being best in class at the end of the map (best medic, best soldier, etc), because they have no equivalant award.
There’s no equivalent for attackers. There’s supposed to be a mission to help take the objective, and it’s even listed as giving 10 XP, but it doesn’t work, no XP is ever awarded.
