Same old arguments from Ashley.. Over 12 pages he's trying to convince us that his priorities — limiting features for easier support — should be ours as well.
Construct creators have a long history of not listening to their customers. C3 will remain an excellent tool for education and hobbyists, but sadly it will most certainly lose its potential as a serious engine for professional game development.
Edit: To clarify, by "not listening" I meant when Ashley posts something like this, it feels more like an ultimatum than a discussion. No matter what we say or which arguments we present, there's almost no chance of influencing his decision.
