Here is a tip to complete hard battles.Let all units(chose range dps and only 1 melee unit) spawn then build 3 castles and keep all units in spawn point.Then build any tower you like at the edge of the screen till you see the boss then pull it with damage spell in my case volcanic burst.In order to be sure that you'r range units won't die send the leader and 1 or two units that have high hp to advance a bit to they will keep the boss away from range dps.
We should be able to keep units after battles but if they are damaged the hp will not be reseted i mean if i got a zep only left with 30%hp it will ahve 30% if i decide to fight with it.
We need a way to multi-move,recycle and upgrade the walls also we should be able to activate units of different types at the same time(air,vehicles and grounds) no only 1 type.
This is really annoying.We should be able to stack resources in inventory for emergency ok but you will say if this should be implemented why we need mines or compact houses anyway.A number if 50 stacks by 10.000 is more than enough also 50 stack in total so 25 minerals and 25 coins.Think about it...
we should be able to select all our friends at once when we send gifts or it's already possible and i don't know.Also mystery cubes should contain parts,crystals or even chips.
We should be able to move the screen with the mouse.Is really annoying when i play only with the mouse and i need to pull the keyboard to move the screen.
