Hope you don't mind me breaking into your conversation - I have been using EnderIO on Direwolf20 pack and find it a fun useful mod for how I want to play. I have always thought mods like IC2 with the multiple power levels and explosions if you get it wrong to be a pain, I don't want to feel I need to do the equivalent of a college degree to gain the required knowledge to be able to use a mod.The problem with EnderIO is, that it only adds functionality other mods already have, the pipes are the only things that are kind of unique but way to overpowered, recipe tweaks won't help you with this one and the EnderIO. The only real reason, why people want to get this mod is to make the whole pack easier, because they really enjoy the easy piping system and are not ready for something with great game depth like the Gregtech pipes, because people always want to keep their habits even if they could try something new and maybe better.
I am reminded of a conversation I had with a friend who has not played for a while but looked at the additions in vanilla 1.8, he said he thought the armor stand were "stupid", I said there is a simple solution "if you don't like armor stands.... don't craft them"
My point is that nobody is suggesting that Kia stop making cars because they 'only add the functionality other cars already have', the beauty of modded minecraft is that there are many mod packs out there, if a pack has a mod you don't like you can remove it, choose a different pack or make your own mod pack. And there is no need for anyone to argue a mod does not deserve to exist simply because they prefer another or don't like how people use them, mods will only survive if enough players like them.
