Okay, so I have seen this HUGE AS HOLY JALAPENOS ON A STICK debate everywhere all about servers banning or not banning items from Equivalent Exchange (personally wish this mod would be banned less and get more love, but hexplosives are too fun to abuse).
I would like to propose a simple (in writing, not implementation I bet) solution:
Seperate the magic ends of minecraft and the modding from the technologic side (cue dancing robo-baby).
Take the awesome Buildcraft and IC2 and all of that technology stuff to a technic pack for smp, and create a seperate magic pack (eldritch pack?).
For the tech pack, make a label, telling players that magic has been removed from the pack, and that technology now has the full reign.
For the mage pack, make a label warning of the dangerous explosives and stuff, so that players and server owners know (and therefor will not complain about this) what they are getting into, and will plan ahead.
TLDR: Seperate magical mods from the electronical mods, giving them their own seperate smp packages.
Sounds like a good plan?
If you have any disagreements, or know of any way to make this suggestion any better, please refrain from being a troll or flamer, and post a respectful, relatively direct, and well-mannered answer.
Thank you for reading!
