To be honest, SpS/SkS is a problematic stat in this game. It's either avoid like the plague because it misaligns elements of your rotation, or stack it to reach a specific breakpoint. It has the widest tier gaps, so you could have 80 stat wasted without realizing because you're just short of the next tier breakpoint. Too much of it creates double weaving issues, especially with poor latency.

I'm surprised they haven't removed it and replaced it with a new stat.
