Those have been out for a long while. I was kinda angry at that because I liked them the most out of all the engines. Forestry was taken out I believe because it was outdated and taking too long to update.

I am a co-owner of a server I like to play on. Me and the owner debated this for a long while and came to the conclusion that we hated the whole system of condensers and "powerflowers". We banned them because we hate the idea that people can just sit in their base and get free mats without doing a speck of work. We banned all things (Relays, Collectors, and Condensers) because we figured it would extend the longevity of the people on the server. If I do everything there is to do on a server I don't see a reason to play it anymore. Having these things banned provides us with a real sense of who is actually dedicated to our server and who just wants to skip all the work and get everything done fast.

Ruby is a better choice than Iron. Ruby has the same durability of Iron (512 uses) but mines as fast as a diamond pickaxe, but it cant mine obsidian.
