I think the main problem is that what can you do to stop the grind? The best way to increase the amount of XP is to have more advanced content. However, it should be grouped to ensure that you don't end up mashed to pieces. It's like Dungeoneering. This high-level content would either offer food or pots, or cash you can buy food or pots. They need to ensure that it's not a bottling.
Interesting issue regarding gloves vs chaotics. I'm not sure what the varying times of balance are between gloves and chaotics: certainly the quests and levels of combat required force you to have more skills (on an effective team, you could get to chaotics with purely a strong combat ability) but still require you to put in some time. Although it's possible that they've misbalanced the content however, it's also possible to discover 90+ weapons that have more requirements right across the street.
