I was waiting on expert mode as well and was kind of disheartened at the change. The thing is no one knows what 1.13 will be, just like they didn't know what 1.12 would be, other wise they would never have started on expert mode back in April. So to say something like 1.12 is a good stopping point is kind of pointless because if Mojang comes up with something just as good or better I can already hear, of 1.13 has this great new feature that going to totally be awesome forget what we said about 1.12 or 1.11.2 or 1.10.2. My point is why scrap 3 months of work? if I were to do that in a company and say hey this new software came out so we are going to scrap this, I am sure this new software is going to get us where we need to be, don't worry about fact we are flushing 3 months of development. My personal opinion is finish what you started, give Lex and CPW time to stabilize 1.12 in Forge before beginning development on the next generation. If 1.13 has something even better then 1.12 what then??? More nostalgia map rewrites while you drop back and punt again? To not finish what you started is a waste of time and resources unless you never intended to finish it anyways. Just my .02, it might not be the "Wow Gee thanks for all the great work on free stuff FTB, but it is what I feel like now. How many mod devs and mod pack devs are going to get burnt out trying to keep up and say screw it and move on?
