I have really liked the encounters so far also, but, I would love to see some overland dungeons put in, and just in general some VERY hard content.

Or, maybe just whole dungeon zones would be good.

I'd like to see beastmen zones wherein maybe agro works differently and mobs WILL not break away chase unless you zone out, or I've heard tell of ff11 having strange agro rulesets like undead all agroing across zone if your really low on life, some flavorful zones like this would make this great game even better.

Id like to see insane or even impossible content added, in EQ I cant recall which dragon it was but they meant for it never to be killed, it was an impossible mob, and that's kind of how eq raiding was born, an organized group of players got together (like 200) and managed to kill a mob that was meant to be impossible to kill, things like this really add flavor and soul to games and those players will never forget they achieved the impossible.
