? no you don't.
You pick Value Disposal and Grand Welcome at the start of the run and never bother about resources ever again, you always get Hell's Chicken on F2 for Sharp Needle which should do in any run since it's the best for speedrunning MD.
There's no other pack or gift to hunt, the starting poise gifts are fine and any other random poise gift on the run works, you only need to bother making the non-fusion Tier 4 poise gifts (clear mirror and fragment of conceit), then upgrade mirror.
You don't really bother switching units, you just randomly click any 1 or 2 that are still alive since they will all die in 1 shot along with the entire node, if anything survives, you just EGO again.
>RNG fucks you during KoD fight
No idea, but you could just pick any other theme pack, KoD is already a big slow fight which goes against the idea of doing fast runs.
Fellsang runs take literally 10 to 15 minutes, because is just turn 1 corrosion -> win -> next node
The only real reason not to do it is because you don't have starlight to pick starting gifts, which is more understandable.
