Wurst is an open source project, and for that I respect the developer for making it open source. However, it is indeed not the best hacked client (obviously).
I have 5 years experience with Java and 3 years experience with minecraft modding and hacked clients. I'm working on my 16th hacked client right now (I lost all my data while I was switching operating systems; silly me forgot to backup files), and it's pretty good so far. It's a 1.8 custom hacked client (by custom, I mean I edited Minecraft's entire codebase and removed all the shit that weakens you, brings you down, and stuff like that), and if you'd like to help me test it and use it (it's a bit different and has way less features than Wurst, but should be better than Wurst and is more high quality), then hit me up with a PM anytime. It's probably gonna be a private client for a future team or some shit, or I might sell it and save up for some tuition money.
