Thank you so much for going through the details. The meat of what you say (i.e. if your damage through more crit + SP makes up for the miss… then surely it would be the way to go)… is conceptually how I understood it… and why I happy to trust MrRobot…it just seemed logical to me. Your addition of the hard maths will hopefully help get the message across to the doubters… or give them something to challange you if they still think its wrong. Either way, we hopefully edge towards a common understanding… and things get/stay aligned.
In answer to your question re Corruption… yes…in raids, we dont have enough debuff slots for all locks to use corruption… so we tend take turns on who can use in each raid (even then … can still see it get knocked off 
)
So thank you again for taking the trouble to explain (again? your first reply made it sound like you been through this a hundred times… may be pin it? 
)
If I feeling brave… I may post this thread into the Warlock discord (the hotbed of “you must go hit” I understand) … so you may get more “feedback”.
All the best
