Strongly disagree.
Shinewood has been designed around the concept of having two entrances, Tullan & Halien. And it's not meant to be farmed forever, they have already mentionned that they work on a new area with new special monsters.
The fact you can't have more spots is up to you deciding to unite with half the server, not about the amount of monsters.
You won't motivate anyone to come back to play in the current server state and certainly not by adding more monsters to any place (just look at eclipse, it's empty even post-tesseris changes), y'all have abused everything too much, it's too far gone already.
