See, some people simply cannot think logically nor can they make accurate comparison. I would go as far as to speculate that he does not even understand a simple sentence like "DAI be more like The Witcher 3". Because normal people understands that one has to play both games to comment.
"One does not have to touch the stove to know it is hot".... again bad analogy which further proves that he cannot think logically or sensibly.
Imagine a bunch of people discussing omelettes (giving feedback to the chef). There is the Western omelette and there is this Taiwanese oyster omelette. Which tastes better? What can one learn from the other? etc. Logic dictates that only a person who has tasted both earns the right to say that they prefer one over the other right? Right?
But there comes a person who hasnt tasted both and starts to claim that they have watched enough food channel program and read enough food reviews to know how these omelette taste like. This person then goes ahead to discuss the difference in texture between these omelettes while everyone else is either baffled or frustrated but it bothers him not. This person than claims that his opinion is as valid as others because he has eaten enough eggs and watched enough food channel programs and read enough food reviews. He knows exactly how something that has never touched his lips taste like. Such is a nature of a Troll.
Since a Troll speaks without logic and sense, they cannot provide constructive criticism. It is also the Troll that will escalate the negative emotions of people who are trying to give constructive feedback.
The morale and feedback of this post to both players and Bioware is: Do not listen to Trolls. Do not feed the Trolls.
