In order to test 'improperly' one must first actually test.I suspect that the 'expensive and lengthy' part of this is why ED doesn't get 'properly' tested before release.
Nobody has asked for a bug-free releases. For the most part everyone understands it is neither reasonable nor feasible for any software to be perfect. 10 minutes of one guy playing though, would have uncovered a huge number of breaking changes in the initial update that should have never made it to a live server. This is not a case of improper, insufficient, or inadequate testing... it is simply a lack of testing. The result of which was completely foreseeable.
Add to that, defensive posturing by FD in response to a player base rightfully up in arms. The attitude on display by Frontier staff ("you've had soo much fun in this game since you paid for it one time a long, long time ago you dont' need to play now") is the cherry on top.
Fix your game, or don't FDev... because of the attitude I don't care. The fact the game was screwed by an update is 1% of the problem. Your handling of it is 99% of the issue, and why I personally will spend another dime on anything Frontier.
Is there a Frontier Jobs page? I'd like to apply I think. I'm a software developer, and I feel the Frontier environment would be a perfect fit. I've always wanted that job where my code doesn't have to be reviewed and pass test suites. I absolutely HATE knowing that if I have a bad week or something and write crappy code, I could actually lose my job for it.
