Seriously, it's ridiculous how much they expect one to pay in crystals to resurrect lost armies. Players have NO idea what level of force is required to defeat the BGs. There is a considerable loss of force when participating. One BG can wipe out your whole defense and then you are left waiting for slow forces to build and for the BG to reset so you can battle lower BGs in the slim hope that you might gain forces.
When you buy Heros with cash, they shouldn't cost as much to revive them.
They do not adequately explain that heroes sent without MASSIVE support armies will instantly die like they are made of paper.
