I noticed that many abilities in 5.5 are no longer supported, unlike in version 5 and its expansions, for example, the "Deadly Strike" ability, etc. Is this intentional?
For example, "Deadly Strike" was previously available to Death Knights (neutral creatures), but now there is a hero in the Necromancer faction who can summon them, and the ability to kill half of the creatures in a stack with a single attack is too overpowered.

The governor
A very interesting idea, implemented a long time ago.
For removing the governor ahead of time, a fine is imposed (rather large, if the term is short), but if the hero attacks the creatures and escapes, then there is no penalty, and he is no longer the governor.
Buying an escaped hero in a tavern is much cheaper than paying the fine.
