The same BB could be moved to level 3.

I agree with you on this point.

Oh yes, there is another fact that needs to be taken into account – in G5 they did something I really don’t like – a small map with very high movement speeds for many units – so either the map will be enlarged or the speeds will be reduced, and in that case no one will reach the opponent on the first turn (unless you have speed tactics and aura, then a dragon or phoenix might make it), which means we need to take into account that it won't be possible to eliminate them immediately (this was mentioned above).

That would be simply wonderful.:smile54:
"Tactics" would finally acquire its true form - it could be used not only to move troops for faster attacks but also to cover and group up without taking damage from level 2 units:smile35: (furies) on the first turn. The tactic of moving around the map would become more significant, as in Heroes 3… In general, all the best things from previous parts are in G5.

And... there is such a mod called "Higher Creatures" /topic/9881/
It has bugs, but there is an idea: building a tier 7 unit requires city level 35. Perhaps requiring a city level for upgrading each unit level would fit into your mod...
