I do not like hybrid or class-based experience penalties (or bonuses).
The original developers even admitted that penalties were a mistake to implement, and they eventually removed them from the game. They were intended to serve as a balance to the perceived notion that hybrids and certain classes were more powerful, but in practice that turned out not to be the case. Forgive me, but someone posted the actual original developer blog last week, which highlighted in detail and proved why experience penalties were a mistake and why they were removed (I cannot remember the exact post). In one way of thinking, experience penalties are akin to a bug that was eventually found and removed from the code, and since many such bugs have already been fixed for the Green server I don't see why experience penalties shouldn't be removed as well.
Personally, I would prefer if the penalties were removed on Green, but this isn't a game-breaker for me since I will not be playing a character with a major penalty. And if they are included they will not affect my willingness to group with other players. I'm looking forward to the social aspects of the game and the adventure itself, not racing to the maximum level.
Actually, I managed to find the post by xCry0x on September 15, which linked to the following EQ Producer Letter:
