If that's the point then it's wrong and failing at basic comprehension. The dev did not say the ghoul could not get crit fixed because it messes with stat weights. He made a broader point that he felt unholy needed more balance across secondary stat weights and that would be looked at during overhaul changes, which will happen in 5.0 along with all the other overhaul changes so as not to upset things mid expansion.
In other words. He ignored pet not getting crit as being insignificant. He made a broader point of what he felt needed fixing in the spec and gave an indication of when that work would be done.
Comprehension. It helps.
The underlying premise of Heartless's question was about pet scaling. The developer extrapolated that into a larger point. All this thread does is deal with that underlying premise.
