Because balance is important for server play. Single player it's typically not an issue, but it's annoying if you play on a server and try to 'restrain' yourself while the rest doesn't. There's a fine balance between making stuff too easy and making stuff too tedious, and it's good if mod authors provide configurations so they can be balanced in a pack against other mods. It's not good if 'new' mods make older mods more or less completely useless with the stuff they add. That's what I dislike about the force engine: it totally blows away other early power gen methods.
So what your saying is, if you have to make yourself suffer, everyone else should? That's fairly selfish of you to say. Who gives a rat's ass if people do shit differently? I see people doing massive, complicated shit with the modpack that I couldn't dream of doing with my feeble female mind. They're doing touch screen, Tony Stark shit fo' cryin' out loud. But you don't see me complaining that shit's too complicated for me to learn so everything should be simpler.
Let people do whatever the hell they want, it should only effect you if you're directly involved in a game with someone, in which case you may have a talk about how you want to play it with them. God forbid you spend a few minutes of your life doing so.
And well hey,
maybe people would like a simpler option for an early game energy method. Maybe what's already existing has already been nerfed to no end so it's hard for people - like me - to get into it.
Do you know how hard it is for people like me to get into these modpacks when everything simple or uncompleted is made into a complex mess?
Bloody hell, I've been trying to get my fiance into this modpack since it came out of Beta.
She's not having any of it. She finds it way too overwhelming, messy and complicated.
It's fine just to sit in your own bubble and say everything's terribly and inconveniently easy when you know it all, but when you're an average or "just starting" player you don't know anything because if it's not already complicated the chances are it will be in the next damn update.
So yeah, just maybe we'd like the simple option in what's designed to be an easier modpack without having to worry about someone tripping up your baby steps.
