Question about Fortification and endgame mobs

[Renothebest]

hello everybody!
I have 3 questions for vets and players who already are experienced with end-game contents:

Are mobs in the endgame (for endgame I mean dungeons most farmed at higher levels) subject to critical hits?
Do they have Moderate(50%)/Heavy(100%) Fortification?
What is the % of mobs with Heavy, Moderate and without fortification?

This is very important to me in order to create greensteel weapons... I have an intimitank dwarf and I'm going for D.Axes since they deal the most damage (un-critted), but I'm also thinking about using Khopeshes or Scimitar in next reincarnation (changing the race). I'm a bit confused on how the criticals will work on the latest contents, that's why i'm asking you!

thank you :)

Some major bosses have 50% fort, which makes weapons with good crits relatively less powerful. You should already be familiar with that from Shroud itself.

But 100% fort isn't really seen unless the creature type defines it that way. You might almost care more about the +2 attack rolls than the crit effects...
