Shaman Spec?Follow

not sure if anyone asked this or i asked this in past lol but what spec does shaman go for, i read other posts on other sites some say Alteration others conjuration, well since i solo/molo they tell me spec conjuration since i do do a lot of doting more than buffing and healing and thru AA's i can 2nd spec alteration.

So what do you other shamans or players that solo a lot spec in ?

I did see someone said spec evocation BUT again most of our damage we do the most is our DOTS, so i don't see Evocation being a high priority in soecing it
