Yet there's a paradox: trainers both liberate and flatten the experience. They free you from constraints, letting you experiment with unit compositions you’d never risk in ranked play, staging impossible defenses or crafting towering, unstoppable columns of steel. But in doing so they can erase the very tensions that make Company of Heroes sing—the fragile balance between offense and economy, the satisfying calculus of sacrifice, the small victories won by clever micro rather than brute force. A perfect amphitheater for creativity, the trainer can also be a dulling spoon if used as a crutch rather than a tool.
