Leveling and Gear in WotLK

[Precio]

So...few questions. Please respond to questions like this: 1.) <answer>

1.) Leveling-wise, I want opinions of the community, would it be faster lvling in instances since it will be completely crazy outside of them, or will it still be faster grinding and leveling up to 80?

2.) Will pvp shields still be viable?

3.) Do you like the look of Tier 7?

4.) With our threat being the lowest already and getting worse come the patch, do you think we'll soon get fixed?

5.) How much trash does Naxx have? Compare it to Kara please.

Thanks for all the responses, just send me a private message if you want the flame the thread.
