This is the part that i like the most

Quote" The initial talent tree selection unlocks active abilities that are core to the chosen role. Our goal is to choose abilities that let the specializations come into their own much earlier than was possible when a specialization-defining talent had to be buried deep enough that other talent trees could’t access them. For example, having Lava Lash and Dual-Wield right away lets an Enhancement shaman feel like an Enhancement shaman. Other role-defining examples of abilities players can now get for free at level 10 include Mortal Strike, Bloodthirst, Shield Slam, Mutilate, Shadow Step, Thunderstorm, Earth Shield, Water Elemental, and Penance.

Having TS at level 10!?!?!? that will make low level BGs crazy fun for shamies! I like the idea that all specs will have class defining abilities early like this, your low level tank WILL be a TANK! I hated having to wait until 40+ to start feeling like the role i was trying to play!
