#1. What I meant was in order to teleport we have to temporarily give people access to our stuff. If we simply want to teleport to someone but not have them be able to access our stuff, we have to constantly add, teleport, remove, add, teleport, remove, which is completely unnecessary. By request spam are you referring to repeatedly sending requests or constantly teleporting across the map ignoring the land inbetween that you would normally have to traverse? In regards to the first, repeatedly sending requests is violating a rule in itself, and I feel that it would be more beneficial to put more trust in both the players and staff to handle instances like this so the server is rid of the pointless inconvenience of friending-to-TP. Additionally, I think I can already spam requests as long as I haven't actually teleported(might be wrong). If the second is the case, I completely understand, but it is still pretty redundant as people will teleport anyway instead of traveling, still ignoring the land inbetween, given that the distance isn't that far.
#2. If you really plan on increasing it, maybe solution I should be suggesting isn't to decrease the cooldown. The main issue that I see people having is that people trading you affects your cooldown. For example, if someone wanted to borrow something or wanted someone else to craft something for them, they'd either have to give the player access, go through that absolutely horrible ever-changing list of friends, add them, teleport, and then teleport home wasting caps, or they would have to wait the timer(apparently getting larger) to get their items back despite their intentions being of good nature. Traveling is always an option, but as mentioned before, that option is usually ignored due to teleporting being a thing to begin with. Perhaps the better solution is to prevent people trading with you affecting your cooldown, that way you can't trade willy-nilly, which is the issue you're trying to avoid from what I understand, but can still trade back people who you let borrow items/etc.
Convenience features can have inconveniences within them. This is why I made these two suggestions, because I feel that there are unnecessary conveniences within these two convenience features. Yes, I'm really glad we can even teleport and trade in the first place. Sure, it could be a lot worse. Yeah, they aren't really that huge of issues. They are so little in-fact that I'm the only one who decided to make a post about it after all this time. Either way, I think just these small tweaks would make these features both hassle-free and still accomplish what you want.
