Its not so much that the server is boring, there just needs to be more content for lower levels.
Yeah there is new content, some made for the higher end (which low rate servers miss). Some of the newer areas might be a bit to easy as soloable for lower than intended levels (possibly).
My personal view is that i feel there should be a little bit more of a variety of items, weapons, armour etc for all to accumulate. what i mean is maybe an armour for level 28 that it half way the ac from 22 armour and 33 armour (just adds a different feel). then maybe (for example) a brace for level 25 that has 0-3 dc and then another brace that has 1-1 DC and 1-1 AC (a hunting kit but a pure DC kit), can be applied to all classes.... i have a few ideas for examples of items to add. Again look at claw necklace and green beads, add a necklace aimed for inbetween with 1-5 DC or 2-4DC adds more variety for both Warr and Sins (sins are better with min DC).
maybe adding 2 types of caves one for leveling and one for item hunting, both aimed at the same level and both giving similar EXP ( a bit mre maybe in the items cave) and have it so the leveling cave drops lower items (to sell for gold) and then the items cave drop items for the level aimed for at the cave and the subs and boss's dropping higher tier items to prep for when we level. Obviously add the odd item ( at a higher rate) to the leveling caves to keep people hunting, but just not a complete higher level of items like the hunting cave.
