quote" the power of 4 shamans is our ability to cast 4 lvb at the *SAME* time"

The thing that makes boxing shamies powerful is stacking totems.. mass chain heals..self rezes. Not being able to manage laval bursts perfectly will not change that. And for PvP its the first round of LvBs that matter most. And you will still have the first round go out at the same time.

All this means is that, unless you find a way to hotkey it, you will have some wasted time on lava bursts that are ready before your macro is ready to cast it. So not optimal, but far from the end of the world. Shamies will still be the best class to box imo. And from a solo perspective, I'm excited about all the changes so far ( as long as most of them go live ) My main raider is one of my shaman!
