Your role in a group or raid will depend on which talent spec you decided on
Shaman End-Game Information:
One of the main things that a Shaman can learn is which totems will help their party members at any specific time in an end-game instance or dungeon.
Your role in a group or raid will depend on wow gold which talent spec you decided on. For example, those Shamans who chose Restoration talent specs will be placed into mostly healing roles.
So, you should make sure that you learn everything you can and practice it as much as possible when you decide on a talent spec so you will be able to provide the best possible member for a group or raid.
Within this training, you should learn what your limitations are. For example, you have no way of controlling a crowd or to completely wipe aggro, so you need to learn to be cautious and keep a constant eye on your surroundings.
You should always know when you need to throw up a shield or totem, and you should know when to kite a mob to another area. This can make all the difference in an end-game dungeon.
Also, after you respect you can check out the other power-leveling guides and you should be able to follow them.
