1. All races star bases move
No. Only moving Vasari Starbases make sense based on their Nomadic Nature
2. Phase jump inhibitor built into star base. What percent should it be? Keep in mind phase jump inhibitors for planets are usually 700%
No. That's what the tactical buildings are for
3. Revamp Mines on Advent and Vasri
Absolutely. Mines are overpowered currently (but remain an excellent idea!)
4. Starbases take more money and time to construct in exchange for more firepower
No. IMO, they're already very expensive to develop and the Civilian upgrades are pretty dang awesome
5. On Planet defenses (Planet to space weapons). Extremely Expensive.
Yes, iff I understand what you mean. I think you mean adding a planetary improvement that allows planets to return fire. I agree 100% and it would make sense for all three races, but balance will be very important on it so you can't just upgrade your planets and forget about them!
6. Planetary Shields for starbases.
No. Starbases already have shields (but not a bad idea!)
7. More than one starbase per gravity well
Yes, but only 2 total. This way you can have a civilian SB and a Military, or 2 of both.
8. Interplanetary Star base travel.
No, but reluctantly. While it would make sense for Vasari to have SBs to move across planets, that would over-power their already impressive armada (especially since it can be used as a jump point)
9. Mine cap limit individual of tatical slots.
100% agree
10. Space Ponies
Heck yeah! Space Ponies for everyone!
