The pros: If I have a house/realm 2000 blocks west of spawn and one 2000 blocks east of spawn, I don't need to take ages to get there, past giant walls in private realms.
The cons: It's overpowered, especially with the coords thing, because you can tp pretty much anywhere. Why would anyone walk? Plus, you would have no reason to make bridges, etc. if you could tp frequently. I support limited warping, but only limited warping. I also the 1500 rc wouldn't be much to those people who can converse through /ads.
IMO it would be better to have a way to get multiple "/home"s, but only if you could justify the creation of each one past the first to a mod, although that would annoy the mods somewhat. Like you could do /sethome2, then it would say "Your request has been sent to a mod, and shouldl be replied to within 3 days." Something that allows for multiple homes, but also lets the mods/admins have some control over how many you can have, and where, so you couldn't make random /homes in a place you think you might maybe want to visit again sometime, or something like that.
TL;DR: I support more warping, but only in mod-regulated multiple /homes.
