UNIT - Creature Balance + Visual Changes

Shields tank worse – the most important condition for a tank is that the tanking units should not be lost.

What about Ingvar? Shields tank excellently under him.

If lizards are used for breaking through, they often die. Could you give them "agility" and more HP? (One upgrade-damage dealer, the second - a semi-tank).

No one uses lizards as a breakthrough unit, and they won't, as long as there are hunters with invisibility. Even if the Lizards go to the light faction, although they might be used then. There's no point in giving them HP, it won't play any role; they already have very high speed. Instead of HP, you could give them defense.
