Crafting Legendary Melee Weapons

Should it require a mutagen instead of a missive in order to craft a legendary melee weapon?

Right now, crafting requires:

Accessories - Wendigo Spirit
Armor - Aetherial Missive
Caster/Ranged Weapon - Aetherial Mutagen
Melee Weapon - Aetherial Missive

It looks like there are more armor legendaries than other items. So needing to use missives for melee weapons as well is too taxing for that ingredient. It also gives caster/ranged characters an advantage because they can use all of their ingredients while melee chars must decide to focus on weapons or armor first.

I guess its not too big a deal because you can convert ingredients at the cost of 10k but it just feels off.
