If you don't raid in savage this post is not relevant to you, feel free to skip.
I main WHM and when SAM came out I leveled one and practiced & geared it on my off time to try something new. I'm pretty solid with it today, but I'll say this, it's really unfortunate that sam brings nothing other than dps.
I'm not going to say that sam is bad or that they need buffs. They do plenty of dps, are a fun class to play, and even at the highest levels in ultimate raid dps can be plenty high enough with a sam in your party. However, everyone is naturally somewhat selfish and the fact is that if you have a sam in your party, others in the party will not post as high numbers. This directly leads to statics not taking sams, PF groups omitting them, and group morale suffering in general. The same is true for black mage.
When the next expansion comes out I sincerely hope that square can adjust dps only classes so as to give other players an excuse to find them acceptable.
