They don't play on higher difficulties. Most of these complaints are rehashed and not personal, evidenced by the fact that everyone brings up buffs in their rhetoric, when at the game's default difficulty they're not remotely required for progression. You may need a specific buff here and there (the game hands you a See Invisibility scroll early on in one of these instances, just as an example) but prebuffing an entire list is something that's more for Core and above.
