Wow, thanks for all the feedback. I will definately give some serious thought to coming back. Sold my secondary PC though, but upgraded my main PC (i7 920 water cooled at 4.3 GHz with 12GB RAM and an 2nd gen. Intel 160GB SSD ). Might have to upgrade my old 8800 GTX though :P

How hard is ToC heroic compared to the regular heroic instances? And are there any group friendly quests with the argent tournament?
