Heroes 5.5 WarGame Edition - Tactical Edition.

1. I fully support everything said above
2.

It is quite possible that we will set the capture of the Dragon Utopia to be normal for week 3 (endgame), but knowing some players' ability to take incredible guards, questions arise as to how large the guards should be so that it definitely cannot be taken in week 2, but is normal in week 3? And is such a separation even possible in principle?

here we just need to identify all tactics for such battles and make them unfeasible:
- one of these tactics has already been removed - the "vampires under BDP" tactic is practically unfeasible, as a Necromancer cannot fish out BDP; of course, playing as another race you could capture a Necropolis, build up vampires and smile broadly, but it's far too difficult — you'd have to make a number of sacrifices, and you still have to find and reclaim the Necropolis)
- another such tactic - "Chaos on invis" is also cut, since I understand invisibility will be reduced to 2 turns, and Chaos in general has been seriously weakened
- the "Berserk" tactic named after the same-named spell - no comment here as everything is already clear; for similar spells, we could try introducing a level restriction — like you can learn it upon reaching n-th (for example 10th) level (I am considering introducing such a restriction for all 5th circle spells — idk maybe it's not worth it of course)
3. regarding the renaming of perks - perhaps "looting" should be renamed? because the perk's effect does not match the definition of the word:
looting was understood as the theft on the battlefield of items belonging to the dead and wounded.
