8 DIFFERENT units to the battlefield. To explain this idea in more detail. You still need to select your traditional 3 melee units, 2 ranger units, 1 support, 1 spellcaster, and 1 giant. No more any one of or any areas (nein 4 melee units, 6 ranger units, etc.)
I hate having to capitalize or bold words i shouldn't have to... >.>
that's a very good idea why not expand the current amount of units like they did in SW2. Maybe make it so you can only bring a couple of them too the battle field.
They could also create another resource maybe water?
maybe their could be a fight else where on the the battle field maybe under water?
their would be about 3 units under water and maybe they auto fight?
1 would collect water from valves
1 would be melle unit that could breath under water.
1 would be a ranged unit or a spell caster
