You are exploring with your "tank" as main character and the others linked.
A fight starts, you fight and win.
At the end of the fight, it's mostly a battlefield, with fire, poison, water, electricity and so, but The 3 members will instantly go toward the character you're controlling, not paying attention AT ALL at the state of the place, they'll happily cross the poison or get burn to the bones.
Most of the time, when you finish a fight you're not really in the best shape, and having people dying because they are completly dumb when you managed to lose nobody during the fight is really frustrating.
Why not auto unlink character at the start of a fight ? So at the end of it, your members will stay still untill you quietly move them one by one to a safe spot ?
