Wouldn’t that encourage solo play a bit too much tho? Not saying that’s a bad thing, but this game is, after all, an MMO. It tries to encourage player interaction. For solos/small groups, they did cater to them by saying they are adding the ability to create and run your own universe.
Also, it might get rid of the ‘cooperative’ part of the big hunts, as they’re working together for larger rewards. If you get enough from small meteors that may look it’s not worth working with others. Buff small meteors enough and you may also get more from going through small meteors faster than doing the larger ones, further discouraging group effort.
