From the Shaman FAQ on the WoW boards–
5.2 Are there any talents that I *shouldn’t* point points into?
In my opinion, there are four talents that I would recommend staying away from:
* Improved Stoneskin Totem. This talent will increase damage reduction by about 2 hit points for the average shaman, because the stoneskin totem decreases damage before damage reduction from armour is calculated. See my post here http://forums.worldofwarcraft.com/thread.aspx?fn=wow-shaman&t=27379&tmp=1#post27379 for a more detailed reason why this talent is not a good usage of talent points.
* Combat Endurance. From my testing, HP is regened according to the following formula: regen = 9 + spirit/9. With 279 SPI, you regen 40 HP per tick (one tick is about 2 secs). Ten percent of 40 is 4. So, this talent will allow you to regen 4 HP per tick during battle.
* Improved Grounding Totem. Currently, grounding totem is bugged such that any damage spell it absorbs will destory it. This bug has been around for the majority of beta, and it is pretty much been accepted by the shaman community as “broken as intended”, and there is some uncertainity that this bug will even be fixed. Whatever the case, this bug makes this talent very ineffective.
* Improved Healing Totem. Five points here give 20% increase on 14 HP every two seconds. Over the course of 70 seconds, this talent will give 2.8*35 or 98 more health.
