Many times tactician can pose a real challenge for anyone , but for that to happen you willl have to forgo the games main features wich is quicksaving, autosaving and reloading . I'm reloading when I stumble into an ambush and half my party get wiped + all the spells and daily abilities you lost for huge setback even if you eventually win , so I reload and ...but I also position myself, buff etc and wops all of a sudden a severe encounter becomes mundane when you know a little of what will happen, she will scream for help, that guy will run for a drum etc etc .. The elephant in the room is reloading and having trial and error combat possible , not much to do about it more than creating a iron man mode
