As for this:
"And other newer MMOs can do thing more quickly because their foundations of the game support it as of WoW's don't. WoW was made at a time where you don't add new features"
The solution is simple - fix it. Add the tools necessary, work on the engine. That is a very lame excuse and smacks of fan-boyism and identifies with my point regarding the mindset of people that "are happy" with what blizzard gives them: "this is the best we can expect, so we should be grateful for what they can do". That is not acceptable.
If the foundation is crappy as you seem to admit and they don't intend to fix it, I'll rather sub to something that is not rather than get stuck in a rut forever with de je vu - which is also the original poster's point.
I am amused that you basically call the engine old and essentially "crap", go so far as to actually make excuses for it and we should be happy with what we have. Seriously? this is ok?
