I don't agree with custom enchants.. That's also going on the fact I have been playing for many years and remember the good old pvp (no gapples, potions, just a sword and your diamond armour). As for the Auction House, I think it would be a great idea if it was implemented correctly. This would take some serious thought though as not to disturb the balance of the way things run as of right now. Just my input, good ideas though!
Literally just asking to copy archon, could've put it in much simpler words: Change everything factions related Simple
