I belive i have somethings to learn since i have a hard time going over 1850 with my 4shaman and a friend playing full s3 druid.

I got almost full S3 on my shamans 990 spelldmg been at 1800-1840 for some time, starting to get pretty frustrating to not get over the magical line at 1850 so i can buy my shields.
Could be my battlegroup since theres not that many teams playing 5v5 so many of my opponents seams to know how to outplay me.
