2700 entries might be enough if you randomly sampled players from all across the active playerbase.

An opt-in poll inherently skews the results because people with stronger opinions are more likely to respond, and you can't say it represents the entire audience of the game just by the numbers. 2700 responses from mostly hardcore players will yield a very different set of responses to 2700 casual players who've never ventured into EX trials.
