ok if your gonan post this atleast look at the two inter views
Blizzard's Greg Street on new systems in Cataclysm - Gameplanet Feature
Blizzard's Cory Stockton on designing Cataclysm - Gameplanet Feature
These contain alot of information on these press events, along with some info on the new pre-release event.
and this cut out isn't lazy, none of you claiming that it's just lazy have the slightest idea what game production takes, you have to cull things in order to balance evrything, GC goes on to say (whether it was a blue post or in the interview i forget) they never just trash an idea, they shelf it, come back in a few months and see if they have a new way to work it out.
If they put incomplete or unbalanced features into the game what do you get? a god like OP class taht is impossible to touch (early WOTLK pallys/DKs anyone?), you may yet get the path of the titans.
finaly they stated that there could be more to the medium glyphs such as some of those abilities we saw in path of the titans. Please aphael read some more sources i don't know where you c/p that but it's 4 days old not today.
