I think the G.E. update was great for some skillers. I'm glad that if I now want Coal and Iron Ore to smelt steel bars I don't have to go to Falador, yell for an hour long, getting yelled at because I pay too little or my demand isnt matching the miners' supply..

 

Now I can just go to the Exchange, place an offer, finish another task, get back to the Exchange and find I have two nice heaps of raw materials :)

 

so lets say

 

 

 

 

 

there will be an increase in smelting-activity for me :)

You forgot the one skill which i think may be most affected, which is Runecrafting. People no longer able to be there runes thus-runcraft them. And it is now affectively the most profitable skill.
