What this game is missing is:
some caves could be like instances or dungeons or raids in other games. There should be some elite monsters with good treasure and loot and they should be killable by a good group of people.
For example: there is a cave with 1 big dragon and few smaller ones. Small one would need 500UA or 500 melee tank to keep defense up with around 3-4 other damage players (rangers, melee warriors,...). Should have around 5000-10000 HP and some armor as well. Loot could be some q300+ hides, q500+ bones, some pearls, good stones, maybe some good q seeds, some chests for use, some good q cheese, maybe some epic armor with crazy stuff.
Big dragon should be like boss and should have 20000-50000 HP, should require 800 combat skill tank and around 5-10 damage people. This one could guard some chests full of gold, silver, coins, pearls, good q silk or other precious stuff.
That would make things more interesting and also raids or while there is combat with those monsters should be visible to everyone and if there is another group willing to kill boss they can also fight with other group... you know the drill.
