That is an inappropriate basis of comparison, though. You can't just give potencies with a hard cutoff and call it a rotation, because that's not the average GCD value you are calculating. Please respect the loop!
Anyway, I for one find it curious that SE would "bake in" the ~5% difference for most skills but not Wheeling/Fang. The balance was precarious before, and mostly justified by BotD accounting for tons of damage (if you may recall that brief period in 3.0 where the non-positional potency was 100... they were still worth using from the front, barely, but if it’s visibly weak and you need some sophisticated theory work to prove it... so yeah, going to 200 was much appreciated). It rubs against the grain of basically all their older job designs to make skipping the ends of combos a potentially DPS-optimal option and I will find it a bit surprising if it lasts past 4.1.
(Yes, I realize how some--or a non-negative number--of you must feel: right when the world needed that ornery math-hat the most, I vanished. Lo, I am not dead, just burnt out and struggling to keep abreast of standard developments, much less high-falutin’ guesswork theory. Haven’t even checked my Reddit messages in months; if you have sent one or intend to, I intend to reply when I can, but that will likely not happen soon. Still, it is only fair I give notice.)
