Please read the entire post before posting! This initial post has been rewritten to cover most of what people has been asking me as of this writing. When I started playing Minecraft in early beta, I quickly got into the mods Buildcraft and Industrialcraft. These two mods works very well together in harmony. Industrialcraft delivered the machines and Buildcraft delivered the transport functionality. I later was introduced to a wide variety of mods, like Forestry and EE2. These two mods also adds unique functionality and works very well with the other mods. I then get introduced into this new mod called ThermalExpansion, and what it had at that point was a few machines like the pulverizer and the furnaces (and a few other). Most content was fine but what started to bother me was the fact that the pulverizer and the furnaces was much like the furnaces and the macerator from IC2 in that they do the same processes, but they run on MJ instead of EU. What I liked about both EU and MJ was the fact that they were used for different purposes. MJ was for foresty and buildcraft processing as well as several farms, while EU was more used for IC2 processing. It bothered me that you could do this kind of processing for both types of energy. As suggested lower on this page by Vauthil, and I agree with him, that it would be neat to see TE introduce a completely new type of energy, so we can preserve that kind of different functionality between MJ and EU, although that might seem like a lot of work. And to clarify I do like the rest of the content that this mod adds. I later get introduced to another relative new mod called Modular Power Suits, and while I like the fact that it's modular, it's just not as convenient or satisfying to use as the quantum suit. The quantum suit is expensive, or rather it requires a lot of infrastructure to make. One way I'd say to attract users is to add items that instead of keeping a balance, tips the balance over to it's own side, making it seem "better", while it may cast a shadow over things that may gameplay wise is better and more satisfying. While it may have some nice features like integrated tools added by other mods, it's cheap and doesn't encourage me to set up a mass fab like the quantum suit does. It doesn't have same movement as I prefer in IC2. Then there's again that thing about MJ-EU integration that bothers me a bit, id rather see it integrate one type of power possibly decided by a config option. I decided I didn't quite like this mod when I tried it myself in singleplayer. And this doesn't say that I'm insulting any mod authors, I'm just saying some should consider the balance and interaction with other mods when they're adding new content. That's my opinion at least. To clarify and sum everything up, this is pretty much what I'd expect from an item: The item should be balanced in comparison to existing similar items added by other know mods, for example balanced around setup complexity (I'm thinking how factorization handles the balance of the tripling functionality), price and required infrastructure that's required to use the item (IE how much work a quantum suit or redstone cube takes to make). Different tiers, or maybe the item could be restricted to dungeon chests and Etc. It should be stable. It should be efficient in terms of computer power. It should be different from what other similar items added by other mods, IE how TE handles processed items or generated liquids. Why have two different mods have a block each doing exactly the same? A good exception to this is to have items improving that mod, for when it's played with no other mods or very few. IE have some kind of ore doubling method. By the time you have read all above you might have asked yourself "Why doesn't he just avoid using that item?" and "Why does he even complain about this?". Well for the first question I'd say it kind of bothers me while I'm playing on online servers, especially when working in the same workspace as others, because I can't justify why they shouldn't use xxx item while they intend to use that item. It also bothers me that some authors may take these wrong steps of making their mod super powerful in comparison, in order to try convincing people that this is just better and more powerful. As for that other question that I just made up, I really like to get my opinion out here, this opinion is starting to feel contained for too long, although I just started to go into the depth of why I dislike some of the content out there. This is a very controversial topic I'm presenting for you here and I'd not want it devolve into something that better should be locked, like the countless gregtech threads, that's just an example of what happens to controversial topics. With that said I encourage you to keep this thread clean, feel free to post here, but there's no need to insult me or anyone else for that sake. I'd encourage you to share your own opinion too about this topic. This topic is getting long so I hope I covered everything in proper English.
