I pressed "like it".
I agree on pretty much everything.
The only one not so sure about is the UI Addon development from 3th parties.
Sure it can create a lot of bonus. But I see two problems with it.
1. How do you handle it so PS3 user aren't at a disadvantage? This is even more import if you look at number 2.
2. In WoW you just had to use some addons. Without you you coudn't play as good as with it. That lead to the situation that you actually didn't get invites without certain addons. I don't like this. In regards to PS3 user this could led to split of community.
