There is plenty of room its just looking for it, It should'nt be reset because a lot of people have put hard effort into their builds and such as, i think resetting the map would annoy a lot of people; its best as it is i personaly think
“Who are you to judge the life I live?
I know I'm not perfect
-and I don't live to be-
but before you start pointing fingers...
make sure you hands are clean!”
― Bob Marley
I've been on other tekkit servers where some people who've done everything push for a map reset just to start again - if they want to start again they should destroy/sell their house and put all their items in lava. On the issue of space, I think that there's plenty, I've done /rp quite a few times and a lot of the time I'm in areas clean of any human interaction
