Well I know this is not a complain thread and I'm not a "professional" even if I plan to sell assets in future and create an little game. Still I have to say that missing communication is almost always a sure sign of ending support. I saw a lot of programs and games in development "dying" and this where the first signs. I too payed for even pre-GMS2 and own 1.4 Master (throught Humble Bundle Sale). I waited over an year and the roadmap (with some vital comfort standards) is going behind even more. Right know I'm thinking about changing the engine after I completed a few tutorial-projects (some throught paid udemy-courses). It would be a little waste of time and more money for me but better then waiting another half year. To come back to the topic - an unknown future is a really bad premise to get more in contact with the engine and become an "GM-professional" even if you were willing to activly entranch to this one.
