Q u o t e:
They were 30 yrds before path 3.0.8 went out. The reason why they are 30 and not 40 is because of the hotfix they implemented because some shamans were gaining the benefits of totemic focus even though the talent no longer exists. My belief is the patch 3.0.2 radius buff to totems is just excluding totems that are base 30 yrds and only affecting 20 yrd radius totems.
Keep in mind that it is true that there were some abilities that weren't properly unlearned when respeccing- http://forums.worldofwarcraft.com/thread.html?topicId=14274447372&sid=1
Totemic Focus was indeed one of these so it may be true that some players may not have noticed this effect before and are now noticing the difference.
If this is more than just the change from the hotfix, please feel free to report it so we can look into it more for you.
