I see some flawed logic here!I think its safe to say that Blizzard will lose alot of its subscribers
If you're so desperate for TOR to "kill" WoW and steal all of its subscribers to become THE NEXT BIG MMO, then you do realise that all of the community you dislike will be playing TOR instead of WoW, right?
Mainstream communities suck. You seem to hold to that belief. If TOR has a good community at the moment, it's because it's still quite niche. If TOR "kills" WoW, it's going to become the new big mainstream MMO community. Is that really what you want? Think about it.
