I answered the poll, and I don't think it's a bad idea.
1. The poll has 414 people responding to it out of a 500,000 player base of subscribers. Preferred and F2P people can't even answer.
2. It suffers from Self-Selection Bias.
In most instances, self-selection will lead to biased data, as the respondents who choose to participate will not well represent the entire target population. A key objective of doing surveys is to measure empirical regularities in a population by sampling a much smaller number of entities that represent the whole target population. Modern sampling theory is predicated on the notion that whether an entity is eligible for interview should be determined by a random mechanism as implemented by the researcher
In other words Self-Selecting polls, ie polls where people choose to answer them rather then are randomly polled, are always biased and don't actually reflect the true opinions of the whole, but only those who are very interested in the topics being polled on. They are great "for fun" but Bioware should not take the results seriously and if they are interested in polling their user base they should conduct a truly random selected poll.
