I find the chaining and unchaining system as a whole to be really clunky and inconvenient. The standard cRPG method of just being able to click one character portrait to take control of them, and then being able to drag a square to select them all is a much more intuitive and clean system. Having to actively drag character portraits to and from each other is tedious and doesn't really add anything, And the lack of party formation options is really inconvenient too. You can't put tanks out in front, mages and rangers in the back, if you're caught by surprise in a battle you'll start in a jumble. Overall the system feels like a step backwards from what modern cRPGs are doing.
