There is no need to be so hostile. I am simply illustrating a point, that there are many spells in the PHB that require adjudication, and which can be interpreted in different ways, and as a player who enjoys playing spellcasters, I would be playing under different rules for each DM depending on how they interpret the spells. And the more ambiguous rules there are in the game, the more permutations can exist. (I assume you are familiar with basic probability theory.)
Your refusal raises an interesting question: What would you do if I was gaming under you and my character needed clarification on various rules that were poorly written? Would you provide them? Refuse to game with me for asking questions about rulings relevant to my character? Ignore the issue until it came up in game instead of resolving it ahead of time?
I apologise if my disinterest in engaging you on a bulletin board about about issues you consider - and which I might agree - problematic or vague appeared hostile.
If you were gaming under me, in the first instance I would ask that you didn't; I prefer a chair. I would be happy to discuss my interpretations of rules you considered problematic or vague if you thought they would inhibit or influence your choice of class, race, skills, feats, games, spells, items and so forth. Preferably, we could attend to this before the game.
If you disagreed with any of my interpretations and gave me a reasonable alternative, I would accept it with thanks and made sure all the other players present were made aware of it. I doubt that we would reasonably cover off all the possible rulings because some situations - I'm sure you would agree - would serve to highlight concerns neither of us had considered beforehand. That's why we have GMs.
In the event of your disagreement with me during a game, if you could swiftly point out my error (and here for the sake of argument I'm assuming I am in error), I will correct my mistake there and then - rewinding time in the game if the error applies to that instant or otherwise compensating for it as soon as possible.
If my subsequent ruling fails to satisfy you, I will nevertheless proceed for the sake of the game not getting bogged down. I will, however, point out to you that I'm willing to seriously listen to and attempt to address your concerns, in good faith, after the session. If at that point, I feel I have erred to the disadvantage of any player in the group, I will seek to make suitable amends to all concerned thereafter. If we nevertheless end with an impasse in which we both feel that our ruling is the - shall we say - more correct, I would hope that you would nevertheless accept that I am attempting to rule fairly and that we can proceed on that basis. If we cannot see eye to eye at that point, it might be for the best if we shake hands on it and part company, at least as far as the game is concerned, and leave it at that.
I have never found myself in that situation and I hope I never do. I also hope this addresses your magnificently fluorescent question.
