All the exploit fixes from the patch were added to the base game (Aside from save scumming which is addressed as part of Honour Mode and is an option for Custom Mode via the One Save File aspect)
You are just wrong. Some exploit fixes are honour mode exclusive.
Here is a list from the community wiki:
Undocumented Patch 5 updatesThe
community update #25 also explicitly says so:
The stakes are raised higher in Honour Mode, as save scumming - the divisive art of loading previous save games - is disabled. Some of the more powerful ‘unintended exploits’ have been removed for players who embark on an Honour Mode adventure, though have been kept open for players to exploit in other difficulty settings.
Right there. "Some of the more powerful 'unintended exploits' have been removed for players who embark on an Honour Mode adventure."
The first link I posted from the community wiki lists those changes.
For example:
Pact of the Blade no longer stacks with Extra Attack. Previously, a multiclassed Warlock with any martial class could get 3 attacks per action, and earlier than Fighter's Improved Extra Attack.
So if you want Pact of the Blade fixed you have to play honour mode. If Larian considers that an exploit they shouldn't lock it behind a difficulty that people couldn't have selected before Patch 5. That's a half-measure.
