Heroes 5.5 WarGame Edition - Tactical Edition.

The idea is good, but the difference between Low and High tiers (especially at the beginning) should not be significant, and effectiveness should depend on the map, faction, character development, and other factors (variability should be a priority). Reducing the resource gain from resource piles is good. For chests: if gold is only 500, experience should also be only 1000. Regarding starting armies and heroes: I'm in favor of making hero recruitment twice as expensive. It should only be done when a full-fledged second hero is needed, not just their army (for the main hero, it should be cheaper and more effective to build creature dwellings than to recruit them in other heroes at the tavern).
