Heroes V: Seventh Dragon Era

No, it's like this... my favorite faction is the Academy in Heroes 5... the last unit is the Titan... 3 creatures, and the first one is basically useless to anyone; does anyone play with Colossi? If you're building an upgrade, does anyone leave the Colossi and not upgrade them to Titans? I've never played on short maps; maybe you don't have time to upgrade the building and you play with what you have time for; I don't know... but I'm talking about it in general... further, Titans or Thunderbirds... what's the difference between them? Basically, nothing; all this philosophizing about "lightning strike or storm" is just talk... but in terms of appearance, Titans are much more attractive than Thunderbirds... but overall, it's the same unit - one model, the same animations...
Now let's look at Heroes 4; I repeat, I played it a long time ago and don't remember their unit lineup... but it seems that for the mages, you can build either a Titan building or a Dragon Golem building... it's not just that the characteristics and properties are different; the unit itself looks different...
In the example of Angels, whether it's Angels, Archangels, or Seraphs, they are essentially the same unit... but, for example, in Heroes 4, you could choose between an Angel and some kind of Knight... these are completely different creatures... and not just that one is defensive and the other is offensive...
