Here is what i think is going to happen.
Before now, about all of the ess being sold in P2P was the merchanted kind. Almost no P2P'ers mined it. Now, there is no more merchanting from F2P to P2P, and the only ess that P2P has left is probobly the ones that got transfered over to pure ess. When all the essance is up, the prices will go way up (maybe 100 each) and everyone will stop runecrafting. Now, with the runecrafting stopped, all the runes will go up. I think laws will be 500 each, nats maybe 400 each, deaths would stay the same, chaos 200 each, cosmics 250 each, and regular ess maybe 5gp each. This is be bad... I gave it 0\5.
They could've just put 3 portals that randomly changed, and there were 2 blues and 1 red, and the need to go into the red one, and it changed each time you entered. This would be cool
And if you went into the wrong one, you just got teled back a few steps.
I have been law running lately, tons of people get laws and they still sell them for 270-300gp so it didn't change the prices much. Talk about yourself I get my own ess all the time, it doesn't take that long.
