Well how about new main areas for level 100, 200, 300, 400 etc.
There could be a variety of Quests, Shops, a Portal and a relic in each maybe?
There could be a live chat, so people can congratulate people who recently reached 100, 200, 300 etc.
It would save people traveling to Krul Island and the Cathedral of Ways for a Portal/Shops.
Also:
There could be a Buffing Club or something similar, whereby people who are on the spot can sell buffs immediately to people who need them. For example:
Player A needs some buffs, asap.
Player B is selling buffs, but isn't advertised in the FSBox/Shoutbox.
Player A travels to the Buffing Club.
Player B is also at the club, and conveniently sells his buffs to Player A.
The buffing process could go like this:
Player B is selling >Insert Buff Names Here< for >Insert Price Here<.
Player A ticks what buffs he likes.
A message is sent to Player B: ">Insert Player Name here< has requested to buy the buff(s) >Insert Buff Name(s) Here< for >Insert Price Here<" [Accept/Decline]
Player A is buffed.
All are happy
I know it's not in great detail but it can be a working progress.
