For me it’s easily refining liquid morkite. It takes forever. I swear half the team is off staring at a wall while you get the pipes built. Lastly, I can’t quite out my finger on it, but the refining portion feels so scripted and boring…Every other mission type is a blast.
Nooo refining morkite is my favorite! I love figuring out the best way to route pipes and then being able to ride them. My least favorite is probably mini mules, always feels like it takes forever and it can randomly go to shit from the confusing spawn triggers.
