Ooookay... So I'm looking at the comments and here's what I'm doing.

Rain set: This will not be removed. The rain set functions differently enough to justify its own set. In terms of partners(politoad who would otherwise be an enemy, rain abusers, ect), counters(the bulkiest versions of dragonite and gyarados or 2HKO'd by a boosted hurricane after rocks, mind you). If I merged it with the offensive set, it would be a giant essay, that's no fun to read.

Set order: Bunch of people said it's fine already, so that's that.

Offensive quiver dance: In terms of giga drain I was thinking of specially defensive gastrodon, who's OHKO'd by giga drain after rocks as to only being 3HKO'd by bug buzz. Giga drain is staying, though. The ability to restore health and stay alive a bit longer for sweeping is really handy. Giga drain also gives some nice KO's on bulky waters like vaporeon after SR+spikes and a boost. Something bug buzz can't do as efficiently. Even though it's not common, it helps with unaware quagsire who would otherwise wall you if you lack a life orb.

Bulky booster: The reason why it's only third is because Volcarona has some nasty weaknesses. Water, rock, and flying are all very common attacking types, not good for a bulky set up sweeper. Also, volcarona is more built as a offensive, pokemon not a defensive one, which is why the offensive sets are listed first.

Substitute: Personally, I don't really like this set. I kinda want to remove it and make it AC. But I was told to add it so, yehh.

Ev suggestions: They look interesting, I'll run some calcs and see how they fair to the original.

As for the remaining suggestions, I'll add these on right now.

I do hold my ground on volcarona being somewhat predictable, considering you can look at the team archetype, and make a pretty solid guess on the set. Rain team-rain volc. Sun team-offensive, weatherless-defensive/offensive, ect..

Edit: @below I like that too, I'll add it.
