Alliance are the strongest cosmic faction, as it stands.
Think about it. They hold stronger, if not ‘the’ strongest race in various cosmic fields – or have those that have mastered those areas better as opposed to the Horde.
- Fel → Man’ari Draenei
- Light → Lightforged Draenei
- Void → Void Elves.
- Nature → Night Elves.
- Arcane → Highborne Elves (Integrated as ‘Night-Elves’ rejoined in Cataclysm). Not to mention Draenei hold pockets of great knowledge from their once tremendous empire too.
- Elemental → Kul’Tirans for mastery over waters, Dark Iron for mastery over fire.
- Death? → Welp, the Horde’s Forsaken may be born of it – but Kul’Tirans got that cosmology covered too with their druidic arts taking root in the domain of death. If that wasn’t ideal enough, worgen are also ultimate weapons to be used against any undead that arise from that field and are highly resistant (although not immune) to necromancy.
Bonus points goes to the fact that the new world tree belonging to the Night Elves is also born of a great ordeal of souls, poured into a pillar of creation – Forged in Ardenweald and nurtured in the Emerald Dream. We got the Night Elves pumping up a new city with many aspects twirling around the foundations of its birth.
You could argue “Yeah but the Horde has great TECHNOLOGY, with the aid of the goblins!” – but lets face it, compared to gnome ingenuity the goblins are trash. Not to mention majority of the time goblin tech blows up - Even when its not meant to, and would do so earlier than intended if it was.
The next argument could be: “The Horde has boons, and teachings from the Loa to take advantage of!” — Uh, as opposed to the wild gods that the Night Elves have had ties to for thousands of years? Psh’ okay. Not to mention Cenarius. The Wild Gods & Cenarius may be ‘neutral’ – but if their hand was forced, obviously they’re hunking down with the Alliance, as they are obviously closer.
Also on the above subject, lets be honest – Despite many loa being straight up worshiped instead of just revered, the wild gods & cenarius have taught the Night Elves & the Alliance more than the Loa have the trolls or the Horde. Talk about embarrassing, amiright?
I use to think the coolest thing about Vulpera race was the ones that had a pirate & adventurous life-style, so they could at least have some bonus ‘Explorer’ & nomadic points than what the Tauren once held, but apparently the Horde don’t include those Vulpera in their ranks as they’re “Quitters!” for thinking outside the societal norm leaving Vol’dun (Despite doing the same, once joining the Horde lmao).
So there ya have it.
The Horde may touch areas in those fields too with various races – But the Alliance simply do it better, more thoroughly or flex it with more strength & embracement.
Feel free to add more:
— Towards the might & glory of the Alliance and the sad diminishment of the Horde over the times, or the mere nerfing of the Horde & their races to what they could have been — If I’ve missed anything.
