Of course it is biased, write one that isn't. It is clearly and unashamedly designed with the "pro-sell" movement in mind. Perhaps I could have been more subtle and tried to trick people, this is not how I work.
Despite this, there are options for those who are happy with the way it is, which are clear and concise.
In the above questionnaire, "the simple solution" is an obvious bias. The most efficient approach, which the developers are using, is to require everybody to build a non-declinable Magic Academy and then write the subsequent code accordingly.
This statement shows clear bias and is potentially incorrect. How can it be more efficient to write the code then change it? How is it more efficient to code for a building that is NOT removable, rather than the same way they code for most other buildings?
Clearly you can vote against the idea of having it removable, as some people have. In simple terms, this means that while the poll shows a bias that the author has, it does not in any way invalidate the poll itself. I made a statement in the comments that I am surprised you didn't pick up on.
However you cut it, 20% are for, 60% are against. Put up a biased poll to keep it and let's compare.
EDIT: So you support that the Dev's poll was even more biased, as it didn't offer a negative (sell) option?
