Orphic can you update your analyses soon please lol
Anyway I have a couple of things to bring up:
HP Fire might actually be worth the first slash on defensive because of Ferro and Pawn's popularity, QC thoughts?
You still need to change the offensive spread to add 4 extra Speed EVs because of HP Fire's Speed-lowering IVs
Also I have a couple qualms with certain sections. In the Overview I don't really like how Mismagius is the only Pokemon listed that can take advantage of Plume since it's really not ~that~ amazing of an answer (gets worn down by constant Giga Drains, doesn't even 2HKO with an unboosted Shadow Ball). I would note instead that it has a lot of weaknesses to common wallbreakers (Mesprit, Typhlosion, etc) as well as leaving it prone to being overwhelmed by stuff like Lilligant or Ice Punch Gatr.
TWave support is honestly far from necessary for defensive Plume lol, also Tomb is mentioned in TO for both sets so remove pls
Mention a bulkier spread with max HP for the offensive set in Set Details
For UT of offensive you should really focus more on what it
can do rather than what it can't, I mean it's fine to mention it's less bulky than the defensive set but it would help to elaborate more on its strengths
