I agree in the sense that DSS is the best farming comp in terms of damage, clear speed, practical usage and no RNG at all at meme performance (You can macro it). That’s unquestionable, if you met all the requirements, your farming is just the most efficient thing this game has ever seen, way above anything Waver can enable
There’s some variables to consider though: Not everyone have a Superscope (you WANT one for peak DDS), there’s some (rare) situations where DDS doesn’t allow 3T and skill investment is really important, more than any other farming comp ever which poses a problem for new players.
There might be some cases where someone prefers to do a Waver farming comp or the ArcherJeanne+2Brides to have all CE slots at their disposal if they don’t need the superior damage of DDS or they prefer AP efficiency over time efficiency on Event currency. You get the idea, in some specific cases it’s not as simple.
Waver is a more complete package for most people, even more if we factor Hard Content. The peak of Skadi’s farming is higher though, just not at base level of investment and it takes some serious luck or whaling to get there.
