I disagree, it shouldn't be easier to make, in fact, why not change recipe to require Alpha King Titan instead, no but seriously, Gamma King Titan is ridiculously easy to do and gives King Titan at least some(even if really horrible) reason for existing, what's the point otherwise if even blue OSD gives better loot.
Then rather give them some actual reason to exist, some reward that's really worth doing them. The Tek Stove is rather random in that aspect, and it's more gating the Stove rather than giving the Titans an actual purpose. Seeing the crafting recipe makes me think "Oh well, no Tek Stove then", rather than "Alright, let's do Gamma Titan to get a single Stove!".
