Fluorite does seem a little too big, but it's nice that all the rp groups can go somewhere and (usually) have a bit of space to rp in. If the map got smaller in a possible future update, the number of people in the map would get more dense and I could see a lot more of the "omg ur in my/my group's terratory!!1" issues
However, I think it's a nice map and I kinda like how you could run to someplace and not have the local chat be constantly spammed like it is in Bonfire (or, that depends on where you decide to go xD)
