I am a complete world of warcraft geek now. I have a lvl 40 enhancement shaman that I am thinking on changing his spec to resto when he gets to Outlands. I noticed a lot of horde tauren shammies that spec elemental instead. Should I just stick with resto or is it best to have gear for both specs or should I just go elemental for the nature damage dps?
Really depends on what you want to do in the endgame. If you are more into pvp then go resto, I like resto shammies. PVE is nice too for a resto shammy, however elementals get the totem of wrath which is nice for other casters in the raid or group. I would get elemental gear for pve and gladiator resto gear for pvp and pve. The pvp resto gear is fine for doing dungeons or raids, however it is a bit stamina heavy so I would swap in some different trinkets, rings, necklace, and maybe a few pieces of the gladiator set.
Yeah it really depends on what you see yourself having the most fun with at 80. Whatever that is, lvl 70-80 as that spec.
