That's true, i could add mystcraft, but then can't do anything with beta testing.If you want mystcraft you can add it. But I don't like it as a mod, as it kills small servers. As for nether ores that is in the pack, you may have missed it when looking over the mod list.
And pardon my ignorance, but I don't really understand what you mean by "The multiplier should start from nugget bonuses, not whole 2x multiplier by default"
Do you mean that the first time your process ores instead of getting, for example, 2 iron dust, you will get 10 iron nuggets? Or what?
Now, under ''mod list'' in this thread i couldn't find ''nether ores''. Are they under some different mod or something?
And about nuggets, yes. I somehow saw it too escalating when IC2(for example) introduced 2x multiplier. From that on, thermal expansion(pulverizer) gives 2x and a little bonus, AE(grinder) gives 2x from the start, factorization gives 3x(needs some resources to get to that) and so on. Somehow, all the requirements for vanilla recipes becomes just a joke. Even full iron armor, which needs 24 iron ingots, can be gotten with just 12 iron ores, almost from the start - ironically, ore spawn is increased due to machine construction requirements(which are high in the first place due to 2x multiplier introduction). There is no fixing anymore, though. There are too many mods which add easy 2x multiplier.
And also, i'm avoiding gregtech. It just takes too much time to do anything. It's totally different story when dealing with servers though - longer gameplay is a requirement.
So all in all, your pack is more multiplayer friendly and i'm a singleplayer guy, so that's where i should just shut up
