Thinking about making a shamanFollow

I was thinking about making a shaman on horde and had a few questions:

1. How are they in instances?
2. How are they in pvp?
3. Are tehy interesting to play?
4. How is their endgame?

1. Shaman are as good as anyone in 5-mans. They can do just about anything in the earlier levels. However, unless you're healing, you may have a hard time getting into heroics due to your lack of crowd control.

2. I don't really pvp, so I'll leave that up to people who do. (I hear it can be pretty frustrating though, especially as enhancemen.)

3. That really depends on what you find interesting. In PvE both resto and elemental specs basically chain-cast the same spell over and over (with a different spell every few spells if appropriate), relay totems, and go back to chain-casting. Enhancement is basically the same, but they have to wait for cooldowns in between using their abilities (about 3 of them), and get to see a lot of little whirlwinds that accompany their auto-attacks.

4. Resto Shaman make good raid healers and can usually find a spot. Enhancement shaman provide the ultimate melee buffs, but a raid usually only needs one or maybe two. Elemental Shaman do good dps, but their buffs are only marginally better than resto shaman (and maybe worse depending on mana regen needs); there is usually room for one or two in a 25-man (especially if there are no resto shammies).
