Brand New Ground Battle

I think the ground battle system of ES2 is not complex and deep enough. We need a new ground battle system and I have some ideas . Some of them may be useful.

-First of all invading a star system must require planet based ground battles. One ground battle for an entire star system doesn't make sense. We can choose how we use our manpower to invade. We can attack the system planet by planet or we can split our army to parts for a blitz attack. These tactics also will require new Ground battle Tactic cards. Tactic cards may be provided by both tech tree and heroes. There may be a new hero class as tactician. Fleets with such a hero we can use many different tactics or new actions such as assulting enemy city for sabotage or boarding enemy fleet ships. Soldiers in our army from minor races can also provide us some unique battle tactics. A battle tactic that only Mavros soldiers know, will make the game deeper. 

Actually now I dont mind the races living on the system I invade. But in lore there are warrior races that must be better in ground combat than others. We need a race based unit system bring us new units to train for each factions. Each unit has its own unique advantages and disadventges (such as +%30 survive chance in ice planets). With this expansion we can develop new strategies for the general war and each battle on different planets. Some races live in water and some live in air their battle capabilities must be very different for different planets. 

We also need a module system for ground units. We may discover new weapons and armors in tech tree for ground units. Module nubmers may depends on unit types and races. For example cravers has 4 arms and they can use 4 weapon modules. 

for now all planets are same for battling on but it is not realistic. Each planet type should have its own battle effect. desert planets must be hard to battle on for whom dont like hot planets. We can change our units' weapons and armor modules depend on the planet type. Besides there are oceon and gas planets in the game that ground units cannot fight actually and needs different unit types such as ships. (however amoebas can fight in oceon maybe.)
