Chaining and unchaining characters is unreliable and tedious. Hotbar Management is time consuming and impractical - I don't mind some slots for favourite spells, but I don't want to have to create my own, inneficient skill bar and maintain it throughout the game. Almost any other top down RPG did it better. It seems they are copying Dragon Age:O UI, except, you know, that game had little to no reason to switch to other party members, and had limited amount of skills (never needed to use more then one bar).
