Fuctionally, SV is struggling. Even if one enjoys crushing trash pulls with cluster bombs, its not something that brings a lot to the group effort of clearing an instance that isn’t adequately handled otherwise. And this expansion so far, the boss damage is just meh. Mechanically, there is a shadow of an interesting something there, but it needs a lot of work.
There is no reason that the wildfire bombs, serpent sting and chakrams could not be a part of a reworked SV that is designed primarily for ranged, with a polearm talent option that preserves current MSV for the admitted minority that loves it. Serpent sting is a poison dot. KC applies bleeds. The bombs explode.
I’m not sure exactly what old RSV mechanic you are looking for to be brought back (besides a copy paste of old RSV from one particular expansion) but I’d be willing to bet there is room for it in the bare bones that are left of SV without BfAs borrowed power.
