I'd like to start with #4.......I 100% vote NO on this.....this option could and would be horribly misused for potentially nefarious purposes......This game already has that ability in SS groups.
7: Remove the troop influence bonus in Oases. Its a complete and utter waste of troops......coupled with the fact that it turns into a troop pissing contest to get that top % bonus. Influence in Oases should at the very least be population based. Perhaps troop bonuses could be baked into Oases by some means...maybe by your population.....the higher your population the higher the bonus....with a cap of course.
