Intresting fact.....
4.1 will be coming about 5 months after the launch of Cataclysm expansion - the content... is 2 rewamped raid dungeons into 5 man content.
2.1 patch in TBC came 5 months after the orginal launch of the expansion. It had an entire new raiding content even tho That expansion launched with great 10 man and 25 man ORGINAL raiding content.
Now Blizzard is telling us they are sending content out on more frequent basis in smaller doases. Thats just lies. They are trying to fool ppl. Heroic versions of raid content is NOT new content. They are doing about HALF of the conent they did in TBC claiming they are doing more...
