All valid points , expecially your point on mainstream packs preferring simple mods . It ' s one of the many criticisms I have of the FTB team . I ' m not convinced it ' s realistic , though . Mods would effectively need to balance their mods twice , and some mod developers have trouble doing that the first time around . The dev of Immersive Engineering made a post here when it was fairly new basically saying I ' ve spent a month making this mod , but I haven ' t had time to play it , so I ' d like this sub to help me balance it . Balance is challenging , and the community also tends to expect documentation , lots of config options , Minetweaker support , cross mod integration , an API , and a lot of other stuff on top of being a fancy mod for the current version of the game . Expecting mod authors to have two progression systems and balancing schemes for a small segment of the community doesn ' t make a whole lot of sense .
