Take away the ability to earn xp for 2042 in Portal.
I don't see the need to have XP earned in Portal for the 2042 experience and would like to see that element removed.
Portal is a great place for anyone to create awesome experiences that have almost limitless options for those wanting some light fun, or those wanting some real challenges not limited to the 2042 world.
I see Portal, currently, being a place to create/go for players to look for ways to abuse the progression needs for 2042.
Progression that is not needed in Portal games.
Leave Portal creations for the creative, those that want to create or play something different, unique. Don't let it remain a XP farm.
Players can still solo, squad play to learn and unlock many elements in 2042.
Play 2042, earn 2042 XP.
Play Portal, experience a new weird, humorous, skilled, creative world.
Don't mix them.
