It was originally comprised of
- Tool specialization
- “Other” / indirect throughput / self-support tools
By TBC it also included…
- Self-buffs (including MP restoration)
- Party buffs (MP, Crit)
- Munitions
…which WotLK built further upon.
Auras are now class-wide, if present at all…
- …though there has certainly been good reason to ask for a Crit buff aura to be returned to Hunter if/when Hunter might lack for throughput or fitting niche enough for even a single Hunter to be taken)…
…and granting party MP is hardly worthwhile these days.
By the end, then, its primary themes one talents towards/into were centered on…
Today, its primary themes one talents towards/into are…
The largest difference is merely that, especially since Shadowlands, there’s a lesser emphasis on procs and a more pervasive emphasis on stacks as Mongoose Bite is painfully free and a couple former proc-based skills/passives have been lost or mangled.
I wonder why this one would strike you as odd, though? You use poison-dipped arrows and there’s often been overlap since WC2 between the war-painted swampland rangers or berserkers and darker or shamanistic arts.
Why should an arrow that’s already been cursed with manifest enmity (originally of/towards a Ranger-esque favored enemy) be so out of place while an Arcane Arrow is not? It’s not as if the one is any less likely to be pre-enchanted than the other.
Meanwhile, Black Arrow saw its thematic ‘cursed arrow’ precedents among those same older guerilla warfare specialists, silent and deadly, that’d brought us Serpent Sting and
the likes even before Sylvanus’s conversion to the Banshee Queen, while Explosive Arrow can be rather… contradictory for such purposes (no real burst nor collateral advantage, but loudly explodes multiple times per shot).
I feel like they were all fine, honestly, but if something were a better thematic fit for the behind-enemy-lines, deep-forest/-marsh survivalist, I’d have thought it’d be Cobra (not of the snake-catapulting variety), Serpent, and Black Arrow more than the likes of Arcane and Explosive Shot?
