As someone who has played the game and read mmoc all these years, its hilarious how something that was completely hated before is now asked for. Some of the most active threads were all about how Valor points and Conquest points FORCED players to run boring dungeons and how raids only gave 30% of your weekly valor and you had to LFG to death and how if you miss a reset you were 1000 points behind, etc.
No, I dont want currencies back. The -forging system is actually really amazing, the only downside to it is items being able to go above +15 ilevels and the randomness of sockets.
1) Cap TF for gear at +15, weapons at +10
2) All rings and trinkets come with a gem socket, no other items can get a socket
This way you have a balanced system that can be exciting but also not driving too much of a gap based on luck.
