The sad thing is, the devs know that even after all this outrage, people wont really stop p(l)aying when crafting gets screwed over. Sure we will be peed off, sure we will cry on the forums, sure we will feel -insert an expletive here-. But since nobody (or a very small minority) is hooked on the game because of Cannith crafting, I do believe that only very few people will actually do anything to hurt Turbine, like cancel their subscriptions or stop buying TPs. And most of those who quit will be f2pers and by definition, that doesnt cost Turbine money, might actually save a bit.
What really astounds me though is the "we are on a timetable, wont be able to fix the patch before it goes live" attitude - ok, timetable for what? Either you have a set date for patch 10.1 no matter what the patch entails (=you have to release A patch, even if you know its detrimental to the game) or you have a set date for patch 10.1 as it is (=the **** in it IS planned and not "unintentional"). Either way really only shows poor managerial skills from Turbine, because who cares about the deadline? The bulk of your customers dont even know about a deadline, nor do they care - so if there is a deadline, its a deadline just for the sake of having a deadline. And arent deadlines in IT development more of a guideline thing anyway, not real unbreakable rules?
If its the latter though (=the **** in it IS planned and not "unintentional"), then your sincere and apologetic response is not so sincere after all - and Im afraid I agree with the others who said theres just no way you could have "accidentally" screw up those recipes, because its not only about the recipes, its also the item descriptions and stuff like that. Thats like saying "It was an accident officer, he fell on my knife, I swear! And then 25 more times..."
Also, if you cant take out changes in the recipes out of the patch without a lot of coding effort, Im afraid youre doing your coding wrong. That should be only about editing database records, not really changing any actual code.
