You mean in this topic? [Updated for Dragonflight] Munitions - If RSV was to return
Or do you mean one of my older posts? I recall in the one linked above, you do touch on elements pertaining to the complexity or rather partial lack thereof with older iterations of RSV. Nothing much regarding supportive elements, at least not something like the above though.
Doesn’t the website save drafts automatically if it’s somehow closed down or similar? I have noticed some glitches, especially when browsing/writing a post on the forum through my phone, although nothing as big as the complete loss of a draft.
Sorry to hear that…for both of you.
On this topic though, I still recall Viper Sting and Aspect of the Viper, even as a function in PvE. The most noteworthy one for me was when using those two on Lady Deathwhisper in ICC.
Basically, you could pop them both while hitting her, and it was enough to fire off 1 single Steady Shot + Chimaera Shot, and you had replenished your whole mana pool within just a few seconds. 
More often, especially a bit later in the tier, it was enough to just keep Viper Sting up on her and you never went oom.
Not to mention how it(Viper Sting) actually helped to drain abit of her mana over the course of the fight. Referencing the ability: Mana Barrier, which she uses to replenish lost health. No massive amounts since the amount drained was based on the caster’s mana(myself), and not her own, but still, it added up over time.
