TLDR; Slam is not a major feature of (large) Shaman. It's something you'll rarely even remember to use at higher levels, and even when you do it won't work reliably ... but if you're lucky it can be helpful in clutch situations when battling a caster.

Personally, I took it off my action bar by 60 at least, and probably long before (but it's been so long I don't remember). Still, every once in a blue moon when I'm soloing a caster, I'll SHIFT + 2 and use it from my second action pane.
