The armor destruction/ignoring capabilities of throwing weapons however make hybrids very versatile and extremely effective against Chosen and Ancient Undead - fights in which a specialist is useless.
And useless/weaker against everyone else...
I guess it depends on your playstyle, my 2H army has no need of hybrids, all they need is some good long range support against Goblins/Master Archers/Hexen/Bannermen/Crossbowmen, some debuff (overwhelm) or wounding machine before the impact otherwise.
And killing the ones trying to flee or picking some isolated targets.
Sure, let's discuss. Specialist ranger (bowman) is an elite unit used for sniping priority targets (witches, necroes, them annoying hero types) half across the map. You do need them at their absolute best to perform as intended. Both bull's eye and adaptation help them excel at their task.
As for hybrid throwing shenanigans against chosen and the lot - I think you are deceived by being pleasantly surprised that they do their job. When compared, an average hybrobro will do always worse against toughies than an average two-handed bro would. God tier hybrids with poison are very good against the ridiculous arena foes that the tournament pits you against, but that's about it. If allowed I'd still take a duelist / fencerbro for gimmicky schtick.
Not to say hybrids cant work / are shit, they are just suboptimal against specialists.
I always go full 2H in the arena, except if i have found a suitable candidate for fencing (aka god tier initiative + very good Melee + good fat).
The fencer build isn't a gimmick, with a named 2H fencing sword, he can kill an unhold in two hits. (This involves some Legends damage perks)
