I was just curious. As a solo player, about the only thing I'd be giving up is VIP, since I can't do dungeons anyway. Through mass character copying, it seems like you could quickly BIS however many characters you want, open tens of thousands of lockboxes with saved up keys, build up a stronghold with copied vouchers and crates in record speed, etc.
I'm getting tired of iceskating uphill and was just pondering options. I thought I heard long ago about at least one person doing this and wondered if anyone else had any experience with it.
