Heroes 5.5 WarGame Edition - Tactical Edition.

I understand your point about the patch; I'll probably wait for it.
Personally, I've always found it strange that the Knights are Tier 6 units. A simple guy on a horse, without magic, is just as good as a high-level demon or a six-meter-tall half-human, half-cat with six arms. The Dark faction's riders look more impressive, and they're only Tier 4. I would swap the positions of the griffin and the horse. You can understand why the griffin is Tier 4 (because it's not very big, about the size of a cheetah), but why is the horse so good? The demons have a hellish horse, but it's still weaker.
These are just my thoughts.

I disagree. Imperial Knights should have very strong training, as we saw in the Dilemma of Frida campaign, with a training battle to the death followed by the resurrection of the participants. They should also definitely have combat magic for close combat, something similar to what was in the opening cinematic of the original Heroes - Nicholas was wielding a sword in front of him and casting some kind of barrier (which the devil didn't care about, lol). Paladins could definitely cast something like that in battle, not to mention their legitimate ability to heal the wounded, which could also happen in a battle with some mega-demon.

And also, this is a Tier 6 unit - a very rare unit. For example, in MMX, our team of adventurers goes to beat up Duke Olen, and at the same location are Duke Anton, the EMPRESS, and Lord Kilburn - there should be a lot of high-level units, these are the most important people in the state, but no! If there are 10 Sun Riders, and there's only one angel, but he's very strong.

Actually, these positions have been changed for a long time, as well as some other things:

Monks - Tier 4
Knights - Tier 5
Griffins - Tier 6

Oh... I'm a little sad... will there be heroes in the world who will defeat a dragon in an unequal battle!
