[Balance Suggestion] Have Resoln and Pariden Starting HP/LevelHPBonus be 4/2 rather than 6/2, so more fragile at start but no penalty as they level up.

You could make Pariden and Resoln troops lose 2 StartingHP and then not be penalised per level. So for them it would be 4/2. So they would be fragile when first produced but not lose half their HP bonus each level.
