1. I think that a technique expanded to level 5 should receive an ability or a powerful bonus.
2. We have three classes of technology with abilities that we upgrade for gold coins. There should be a tactic that we can improve.
3. Tactics that give a bonus for the extraction of resources of one administrative zone are not relevant, it should work for the total extraction of the city.
4. TIGER B should appear earlier. Fields have become fast, voting appears earlier than the plant is level 14. Few will play on them, they will also die from the M40 and bombers but the tanker will have a variety, and the rest have more experience))
