It still is. In fact, its hardly an argument that the park NOW is a far better one then it was 10 years ago, its pretty much fact.
The building was unsafe, and had to go. There was no other option.
Unpopular attraction replaced with a popular one. I hate Test Track, I completely hate it. To me, it is a terrible excuse for an attraction. But it is popular, and always crowded. So this was a good move by Disney. Don't forget that this was also done by the urging of the sponsor who was not going to renew if they kept WoM.
Yes, the original was the best of the three.
Unpopular pavilion, with nothing exciting inside it. Yes, it would be better open to experience then closed with nothing going in, but there is really nothing to see there.
By the time Communicore switched, everything inside was outdated and/or already available on the market. The very idea of Communicore/Innoventions means that it will constantly change.
And the only thing that does not effect anything. You have the exact same experience whether or not the wand is there. If it identifies Epcot as a Disney property to the casual guest, then its done its job. But to those who already know its a Disney property ... well, just ignore it. Its not they changed the actual SSE ride to incorporate the wand into it.
