I'm going to vote No because I am one of the few people that have and prefer to keep my spawn set in Roanoke. Taking away /trade would pretty much put me in a position where I couldn't and/or wouldn't trade with people anymore. Not going to run through the Nether everytime I need to do business with someone. Sure I know I could keep my home set in Spawn City but I don't go there often and prefer to stay away from Spawn City for the most part. I'd rather keep my home available for projects, exploration, or our NPC town that is about 2000 blocks from either spawn.
Since you mentioned this isn't only for vanilla reasons I will mention again that it would be really great if you would give us warps to the major staff approved cities and projects. IMO Minerealms biggest draw is the fact that the buildings and projects are built legit without mods. Not that it's a vanilla server. It's not a vanilla server. Why not add a little to help showcase those builds and thus the server itself?
Please implement this.
