actually you can
in order for rotational skills to be fun first of all they must server some purpose, either by being powerful themselves (like Chaos Bolt) or by interacting with other abilities (like elemental's shamans Flame Shock), or by building towards other abilities (like all combo builders) or just by having a natural and fitting place in a rotation (like let's say Corruption for affl locks), note that many of the better designed skills fill multiple of those criteria:
for example Conflagrate is a reasonably strong instant which feels satisfying to cast, while it also builds Soul Shards for other skill to use and at the same time it interacts with other skills (by making Incinerate and Chaos Bolt cast faster)
SnD does not fulfill any of these criteria: it's pretty underwhelming in overall impact, it doesn't really interact with other skills, nor does it build towards them like combo builders do
it's just an boring buff you have to keep up, the equivalent for a destro lock would be if corruption damage got buffed just enough so you now have to keep it up: it would be a boring low damage dot that has no place in the rotation at all, just someone messed up and we now have increased ramp up time without gaining anything really...
will some weirdos say they like it? sure you can find weirdos who like everything on the internet... but they don't matter by any metric, blizzard essentially fell into the trap of adding the wrong parts of classic with SnD
