I think the XP system is fine, I have mastered all 63 skills and found it simple and fun to grind the levels. (Except jewel craft that sucked)
You mastered ALL 63 skills. You have 378 days played according to your banner. That equals over 9000 hours playtime. The average person can't play more than 2.5 to 3 hours every day. That is more than 3600 days of playing the game, or roughly 9+ years. Your opinion probably does not represent the new or recurring player from older times.
And besides: especially you are not in any way harmed by this change. It would actually maybe give ou more players to share your knowledge with, play with, or concerning Naemes argument: give you more players to RP with and enjoy created content with.
I don't see any downside to this. It is just fresh wind for a game that deserves more attention.
