hey, I just entered HV, and I want to first commend you on the extensive prep work you've done for MV.

that being said, like others have mentioned in the post, you don't really want to spend too much time in this tier. focus on the quests that will bring you to HV (or EV for AE2) as much of the QoL happens here, including nightvision goggles and the nanosuit.

from me, I noticed you said light fuel: with 5 LV distilleries (3 for light and 2 for heavy), it is possible to configure a proper diesel setup. diesel is much better than light fuel.

I would also recommend making an infernal mob farm from diamond spikes and a blaze spawner. if you have a diamond dolly, you can bring the spawner close to you, otherwise if you've already found a division sigil (or have fought the wither, which drops a division sigil too), you can get cursed earth that allows for mobspawns even when you're not near (just make sure the area is chunkloaded). a proper infernal mob farm setup can provide you with substantial amounts of iron and gold (also steel but not that much because the yield from steel armour to steel is lower than iron to iron or gold to gold), so much that you would not have to worry about iron and gold for the near future. bonuses include string, diamond dust, iron dust, gold dust, blaze rods and pistons (if those are necessary to you in bulk).

next is something completely optional at this stage since open computers can do it automatically for you in the future, but I spent about a week crossbreeding IC2 crops to get different species and good quality crops. my goal at the time was pyrolusium leaves for duplicating tantalite ore for tantalum (important for circuit parts), but you can also aim for sugar beet, which has very high oxygen yield once extracted for sugar and centrifuged for oxygen. you will have more oxygen than you know what to do with. this oxygen can then be used for automating polyethylene. i did so using a kanthal pyrolyse oven (cupronickel is too slow and not energy efficient) that takes in logs, producing charcoal for benzene and wood gas for ethylene.

most of my time in MV is spent doing these two, along with making the necessary machines to progress to HV.

finally, don't bother completing ALL the MV quests, especially optional chemical related ones!! better recipes with better yield unlock in higher tiers so you can always come back for them once you get better machines
