I will definitely miss the pile of vet rewards that are available for each noob I create, but I will be coming back regardless.
I played from about 10 days after go-live, to the end (except for the last day...I just could not bring myself to watch the servers go-offline), had 25 L50 characters, many at various levels of Incarnate abilities. My son started playing when he was about 6, and also played to the end, so he was practically raised on it. By the end, he had a lot more than myself tied up in the markets, and crafting, but I can tell you that nothing will stop either of us from returning on day 1!
Besides, if you don't concentrate too much on what you lost, sometimes starting over can be fun in its own way. Eventually we will all get back to where we were, and imagine all the fun you will have getting there! Perhaps by then, the 1.5, and 2.0 versions of the game will be in Beta, and imagine how great that will be!
