UNIT - Creature Balance + Visual Changes

Indeed, if we approach this issue from the perspective that Nargott does, then the griffin should be on level 6, and the knight on level 5, but there's another problem here – is it really good that we'll end up with an army where there are no flying units from level 1 to 5, but both are flying on the last two levels??? – that is, it's probably better that similar units of the same faction are not located next to each other, but are scattered across different levels, differing by 3 (+/-1) tiers.
