Is the supply ship quest/ kill 5 world 5 bosses worth the time invested? Yesterday, I rotated through 3-4 different fleets trying to get the required number of kills of aforementioned, and I ended up with a dozen injured ships (each requiring 1-2 hours in repairs, even DDs) for what.... a bit of oil and bauxite, and almost no exp?
The submarine quest that's unlocked is nice and easy and gives nice exp, but I don't think it's worth the entire afternoon I spent. That time probably could've been spent getting my girls to level 60 instead of running 2-2 for 120 exp per fight.
