The best part of the old API was because I was able to modify my server according to it's needs and do it on the fly. I've noticed with all these new plugins that I can't just open a .phar file and change something, and let me tell you, that sucks REALLY hard and will suck even harder in the long run. Not being able to edit a .phar file on the fly is like having an Apple device and needing a jailbreak (because Apple is so insecure about how they feel with their product). With Pocketmine 1.4, will there be a way to modify the source so we can have specific settings to make the game funner for everyone else? People don't realize it yet, but this will be the biggest disappointment for server owners soon to come.
