It’s certainly your prerogative to strictly adhere to lore. I was just pointing out that, unlike Spear of Adun, Last Stand can be made easier or harder based off tech availability which comes from playing missions.
When you play it through the master archives, do you always choose only the units/tech that would be available if Shakuras was done first? I suspect you’d have to if you only stick to lore. Choosing anything else would be equivalent to playing the planets in a different order.
I think someone mentioned it already but I find great train robbery to be rough without tanks. I had to do save loads on hard when I tried it. It’s a breeze though with tanks.
These days I save the all horner missions till after Mobius factor (which is after the Dig). It gives Raynor a nice arc in my opinion. Raynor seems lost running all over the place doing shady errands for Tosh, chasing the artifacts all over the sector, spending hours on end seeing visions from starring into a freaky protoss crystal, all the while drinking, and guilt shaming over Kerrigan. It comes to a head in aftermath of Mobius. But following it up with rebellion missions makes for a nice arc of Jim picking himself up, and get his revolution back on track.
I found both LotV and HotS can be difficult playing on brutal in the earlier missions but the difficulty drops significantly later on with all the macro upgrades and special abilities you get. Ultra mega Kerrigan trivializes enemy armies as does the downpour of orbital bombardment from SoA after more unlocks. But yea LotV SoA mission is annoying on brutal. Last Stand on Shakuras was a fun challenge. I got immortals on Korhal first and upgraded to Nerazim version to to quickly dps air hybrids IIRC.
It was very hard for me as well, but only because of the warp prisms and the nydus worms. Then I realized that they only come after I complete an objective point. Since then I always let all objectives on about 10 life and destroy all at the same time, so the mission ends and you don’t have to bother with those things.
