Buried down in the balance changes are 2 huge changes: Telomeres can only be used if you are the OT, and trades can only be made if you're close to the person. I agree with the first one wholeheartedly, but the second one just made trading unnecessarily more difficult. Now we will have to keep trying to get on the same instance in order to complete a trade..yikes to that. I didn't see a problem with the way it was before.
EDIT: No longer agreeing with the hack change - as I've realized this destroys so much value for those who purchased temtem with plans to hack them in the future.
You don't need to be in the same instance, just nearby in the map.
