I understand your point but will respectfully disagree, you lose some tension being able to save whenever you want sure, but it also negates the times you accidently get things ruined, such as a AoE hits a guard so all friendlies turns against you, you dont want to reload then if you just a moment ago managed to beat the actuall boss and just needed to kill off the remaining low health mobs.
That said, i rarely save in battle, but i can see it to be a desired function for many who is stuck on a certain boss.
