For us... I'd guess they'd have to strengthen the monsters, and probably more, alter our stats a little too. Because on Fiesta, I wasn't able to solo in MT til I was like level 30. On BK I could solo there at level 24. We were able to grind in CP in our early 30s with no problems.
But I think the community would generally dislike it at first. They'd be happy they got more skills, but then they'd noticed maybe a monster takes a little longer to kill, or the monster gives a little less exp, and then they'd flood the main forums with "WTH y u do dat???"
