Hi.

1. The existence of an option to change a decision does not automatically make the original decision irrelevant, as you claim. No: you yourself have to make *another* decision to actually use said option to change your original choice (and thereby to make it irrelevant, if you want to see it that way).

2. It follows that you can simply decide not to use that feature. In this case, your game is free of what you consider an exploit. There is nothing to discuss.

3. You can also decide to use the feature. In this case, you (irrationally) chose to use what you consider an exploit, and you have nobody to blame but yourself for it. There is nothing to discuss.

4. It's up to you if you want/need an in-character justification for exercising (or not) that option. The game cannot hold your hand for every bit of storytelling -- that is one of the core aspects of RPGs. They (intentionally or not) leave a lot of room for you to fill with your own inspirations and fantasies.

5. By the way, this applies to almost everything in a game, particulary a RPG. You feel that pyro spells are OP? Do not use them. You do not like how stealth works? Do not use it. You want an iron-man mode? Do not use the save/load feature. It is child's play to justify every non-meta decision from an IC perspective (e.g. your character has had to witness a parent die to fire and hence suffers from a severe trauma, rendering them unable/unwilling to cast fire spells).

6. However you decide, personally, you cannot legitimately impose your choice in this matter on everybody else. What would be the justification?
