EnderIO = overused? All it has is Item transfer, ore processing, armor, flight (Glider), Item & fluid & energy transfer across dimensions and energy storage. Why would you bother?
To be honest, I feel like enderIO can be improved... it can be a bit resource intensive from what I have seen from streams and in single player. Optimization of how it uses resources or at least processing and memory might help a lot with the lag it creates especially in large complex logistic circuits. Broadly, I have watched in the background a very long time, rarely speaking especially after that double post mistake >~<; however, I have felt like mod authors and mudpack authors have in past 6 months lost focus. I feel like if I don't speak out about trying to always gear mod to improve performance, then another 6 months from now the community will diminish.
In fact, I have asked before if enderIO can be improved.
If, for some fundamental reason, it cannot be improved, then honestly why should it not be replaced? Heck the you do realize that vanilla use of slime block, rail, piston, or filter to transport items and ice to transport mobs is way more scalable than most logistic system simply because it puts less of a "load" on the server. Some of those methods are really janky and server crash heavy, but only after you scaled to insane propertions.
What is the point of a graphics or texture mod if its not usable by a large part of computer configurations? Its like making a replica of Donetello, Da Vinci, Manet, Picasso, Warhole, Pollock, Guche, Armitage, Predock, Fisher, TheoJansen for a blind audience with no audio cues. Similarly, what is the point of quarry or logistics mod if, when scaled, its complexity creates too much lag?
