I doubt ToR makes much of a dent in the WoW subscriber base. While it might be a good game I think the largest draw to WoW these days are qualities new MMOs don't have. That's familiarity and community. With MMOs it isn't always so much that you're playing a game but logging into a universe.
I assure you it will make a dent. Since I have been Beta'ing it for sometime it is a WoW clone for the most part but it tells its stories very differently and not just with the voice stuff either. Theres still a lot of kinks to work out but it looks promising.
The thing about WoW is that a larger portion of the community is looking for something better or a quality alternative to WoW, me included. ToR has that potential.
as for the closing of WoW. I dont really see it ending, it probably will go to FtP once Titan is close or out the door.
As for deadrats trolling...I wouldnt have expected anything less.
Like Hawking74 stated I have a life and I still enjoy WoW. I dont put as much time into it as I used to but I staill raid and enjoy other games. Man I have been addicted to TF2 for a hand full of months now!
