Yeah, not hard to implement.
Okay, this is what the, in my opinion, most important one is:
Y'all probably know classic and all those servers, and most of us love them. What they got that Kingdoms doesn't, are those rooms that are just there. They may contain NPC's that tell a story, or something like that. On G2K2, nearly
every room has a purpose, except on the Starting Island i believe - like the pub with it's NPC's. It's so easy. Just add two houses to Bomboria, make one a storage house, and another one just the house of a NPC, and Bomboria suddenly is a lot more colorfull and lively. Perhaps you could add in NPCs which just walk around a bit in Bomboria, like you see in all those RPG's, and say stuff like 'I've heard you can find special potions in the Underground Dungeon', or something similiar.
The Haunted House also is sooo boring. Every room is filled with monsters. Why not add in that if you touch one of the cupboards, you find something like a book that tells us about the Haunted House? And having to trade everything trough quests... yuck. Maybe a key item should be got by getting some sort of 'permission paper' to explore a cave on, say, the mountain of Dustari. This cave contains no enemies, but there are falling rocks, and somewhere is a key.
To tell the truth, Graal's a lot colourful with the Quest NPC's. If a newbie stumbles on them, he gets really curious

Those are cool. Now add in some that don't really have a purpose.
And the second. Well, since we've got stat potions and nearly everyone has piety, why not bring back stat loss, and perhaps exp loss?
