Sounds like you're referring to Arrow Key movement on your clones perhaps? These keys (if you still use them as default) are great for moving clones up/back or rotating to track a moving target (read: pesky rogue).

As for bosses/gimmick fights keep in mind that you have the unique advantage of running 4x Shaman which for the most part means a whole new set of strats/techniques that you'll never find on Wowhead for boss comments ~

Example: Hungarfen in Underbog.
The 'normal' way to kill him is to spread out, and everyone individually moves out of mushroom range, etc. If the tank drags Hungarfen around and everyone pays attention to shroom spawns then it's win... you COULD try the same with your shammies dancing back and forth ala arrow keys, or you could do like I do. I Pally pull him to the bridge you come up to him on, and I just move my whole crew backwards slowly DPSing and Healing, inching along, never stopping. I shuffle ahead to past where he was standing to the wall, turn around and go back to the bridge. He usually doesn't make it back that far.

You've also got multiple Grounding Totems which tbh is the most OP thing in all of WoW in my opinion rofl ~
Some fights you just steamroll over like Omor because you beat them so unconventionally.

So, really... in PvE i wouldn't sweat it. 4x Shaman = Brute force dps and gadget totems ftw! In PvP i would imagine learning to rotate your pack of clones with arrow keys will make a huge diff.
