@Pareto at some point made a post about spammable TSS
I am not too keen on Lightning BS but Lightning Sigil sounds hella awesome. So maybe they can rework the set into a spammable TSS with support Cold\Lightning Sigil.
This would help differentiate it from other TSS sets and adds a unique playstyle to the game. People not too keen on TSS can just build around Cold\Lightning Sigil. So that’s two stones with one bird.
