WoW lost 750,000 players since the new expansion came out I was one of them. I only came back to do arena and try out the tournament. Give your 85 rogue a go at the tournament runs for 8 weeks and cost me $20 USD once you enter you get 50k in gold, all the gems available and all the best gear for your character. You can enter the tournament matches later on or just dual others for fun.
Just the other day I rolled a Druid just for fun said to myself I'll only spend a couple of hours leveling him. 13 hrs later I was still playing
The game sucks you in. So I deleted the Druid. Just running my 85 warrior in arena's is safe enough. Works out a couple times a week for 1 or 2 hrs.
