I have to disagree with all of these points.
Collision Detection would be a terrible idea based on the PVP configuration. Also, this is a zone based game, with many, many players in every area. No Ogre's blocking Lower Guk, please. Bad design back then.. It remains bad design today.
I'm assuming you never made it past level 10. Low level zones should not be akin to Dark Souls in an MMO. It is very easy to die at 12, especially to bosses in the zone. Rote monsters should not be super hard. I hope the higher bosses are tougher, but I'm not looking for silly hard.
The quest helper is fine. Running around for hours looking for a glass on the ground is just stupid. The game circles areas where objectives are needed, but there's plenty of discovery out there that isn't involved, and adding tedium to quests really adds nothing in my mind. In my two days I've encountered multiple nonstandard quests, also, and it looks like the team made things fun without being overtly tedious which some might enjoy, but fuck that noise.
