Yep, this thing makes a lot of sense. Right now we see a ton of people that deliberately stays at a lower level than they should be supposed to only because they are getting this way a better matching in swb. This issue needs to be managed somehow and i consider this suggestion the best way to deal with it even if, more than to top3 people i would actually grant experience to everybody depending on your total victories and on your winning streaks (like ranked currency) and that the reward is placed in the same attachment advanced refinement runes are. Something like that if for two swbs in a row you are first with a winning streak of 15+ (something that can be achieved ONLY IF YOU ARE IN A FIELD YOU BLATANTLY SHOULDN'T BELONG TO) then you forcefully level up. This way we avoid cases like Toyota in server 240 or like mesmes in server 68 that avoid to level up as fast as possible just to have good matchings.

EDIT: if was possible i would love to have the attachment scripted in a way that at the end of the week selfopens if you 'forget' to do it.
