Arthas and Deathwing
Arthas tends to be considered the biggest force of destruction in the universe because he is very fresh in peoples' minds based on being fairly recently introduced through Warcraft 3 and staring everybody down since then. Remember though that even to break away from the control of the Burning Legion, it required a great deal of cunning and manipulation - he wasn't able to simply overpower them.
Deathwing on the other hand is a much more legendary figure and one of the greatest powers ever to exist on Azeroth. It took the might of all the other dragon aspects against him to force him into hiding. He also knows almost every being on the world will be against him so he wouldn't reveal himself unless he felt ready to take on anything that will face him.
Orgrimmar destroyed in the expansion?
Orgrimmar destroyed? No. Given a bit of a make-over and a bit more iron in its spine (so to speak)? Yes.
Bon le reste...pour les péons comme Ktana et Toxyn, juste histoire de. :
Cataclysm Alt Friendly?
Cataclysm is pretty alt friendly over all. We'll do things that encourage and facilitate alts when it makes sense. (Source)
Ancient Glyphs level requirements
You have to be 85. Our plan is to tie it to Archaeology, but that could change. While fishing can be challenging to max out, cooking isn't all that hard and first aid is pretty easy. Archaeology could be anywhere in there. (Source)
Path of the Titans "gating"
We're saying even if someone beats you to level 85, they can't get very far ahead of you on paths. Imagine that when a new rank is available, the previous rank becomes half price or something. (Source)
Cross-server Instances and rewards as a leader
This was a bit of a miscomm. The idea is that you would be rewarded for trying to use LFG to form a group. A separate feature of LFG is that we allow players to identify whether they are comfortable leading the group or not and then we try to make sure each group has at least one leader. You are probably going to have a much worse experience joining a pug of 5 players when none of them know anything about the encounters.
I think a lot of drama would result from arguing over who should be leader if that incurred extra rewards, as well as encouraging players with no business doing so to lead. Really, the focus should be on the group. The leader just marks (though everyone could do that too) and describes the fights. (Source)
Low level PvP rewards no longer sold by the Officer Accessories Quartermaster
This flew under the radar for a little bit, but Master Sergeant Biggins should be selling those accessories again in 3.2.2. (Source)
Path of the titans
They are intended to be gated, not grindy. The idea is more that you have a reason to keep coming back to log in even if say you need a break from raiding or it isn't your team's PvP night. We are trying to contrast them with actual levels, which players can blow through very quickly if they are dedicated. (Source)
