Gleba was a pain. Once I got defense figured out and wasn't getting harassed any more, it was much easier to focus on my builds.

While I still don't like Gleba, it taught me how to create extremely resilient builds and forced me to fully understand belt logic. (I had an oopsie last night where I forgot about a one-off process I was running and I came back to 4M spoilage in storage. However, everything was still running and it was fairly easy to purge the mess.)

Give it a try again if you can muster the strength. It really did change quite a bit about how I solve problems in Factorio.
