Soon the game will be overcrowded and it will be really hard to get a turn, really all NPCs and Monsters should have a good intelligence (there practising on Harnquist at the moment) though if monsters go all around the sewer, you will have Tefusangs at the start and noobs will keep dying, they should just put a bit more rats inn the sewers and also have another place where the rats will spawn, though they could move but then you move towards harder monsters, just make it move a little bit, though if the rats keep getting overcrowded well if any monster keep getting overcrowded they should make another big spawn point for them, and if it still gets overcrowded then they might have to make another server, i reckon there should be another forest rogue (same loot, same health and abilities etc.)because the forest rogue is a bit easier than the other rogues, and because there is only one (that i know of) it gets overcrowded though not always
