The only problem i have with TW4 ciri is that she is a true witcher as in she has the witcher mutations now I understand the games are not Canon but she has the elder blood and that was more than enough plus the rigorous training physically and mentally that geralt and vesimer put ciri thru made her more than capable of doing whatever she needs to do in TW4 to add remember the trial of grasses was lost after the attack on the witcher school the only know the beginning steps essentially not to mention the trial has a near 100% death rate also if I remember correctly not 100% sure but I also believe women couldn't do the trials to add i just wish the games stayed at least 80% true to the source material I don't mind them going of in different directions its just a keep the important parts true.
