This is basically legalized rmt. And I say no to the highest levels on this.
I view ppl selling plex/WoW coin/The Archeage token things as being no different then those buying directly from RMT. It is literally the same thing without a risk to their account being hacked or credit card info stolen.
I do not understand how ppl can be for a plex system and against RMT. It makes no sense at all.
Yea it ruins illegal RMT... but all it is is making the Developers the RMT instead. Which is much worse in almost every way.
If they do add it should be $30-40 for a 1 month sub token, really screw over ppl for going the RMT route.
