I disagree with you pessimism and your topic. However it's a fair question and I'd answer it with "yes, there is a point to shamans" because opinions;
-Enhancment is great burst damage, especially against soft targets like cloth
https://youtu.be/sw0RYsCDjEk < Some cherry picked examples of enhance owning. Obviously not every fight goes this way tho so this is only half relevant.
-Elemental doesn't depend heavily on WF and is a great PvP spec.
-Restoration is the best raid healer imo (chain heal). But also good for single target because of the armor bonus.
