I'm going to start off and say that I like GregTech. I use it a lot now that it's grown on me. I like the added challenge, because without it I hit end game way too quickly. I'm fine if he edits IC2 and Advanced Machines, Advanced Solar Panels, whatever. That's IC2. It's in his department, and it was added to Ultimate and Mindcrack for a reason. Here's my issue, it's when he starts changing other mods. Quarries requiring IC2 Diamond Drill is ridiculous, especially with GT installed Diamond Drills are quite a bit more expensive. Here is a list of non-IC2 things he either nerfs or edits:
Duplicated Dragon Eggs, this sucks for servers if everyone wants an egg.
Only when used with a certain GregTech machine. And the dupe detection is disableable in the config, for servers that allow duped dragon eggs, so not a huge deal.
Enchantment Table Disable, this is not true by default, but is an addition that shouldn't have even been thought of.
Did you know he has a mod that disables infinite water sources?RedPower Block Breakers, I don't even understand why this is in the Config. What is so OP about a damn block breaker? What if CC isn't in the pack, you can't make block breaker farms. It is false by default, but still possible to nerf.
That's about as relevant as the things you said, since they're off by default.
I agree that should be changed back, it's just annoying.Forestry Bronze, Forestry bronze can be crafted I think with the ratio dust:bronze 4:4, he makes it so that it is 4:2, which is ridiculous as it requires 4 dust to make bronze.
That's GregTech's ore dictionary unificator affecting the output of TE machines. So when you pulverize copper ore, you get IC2 copper dust (or whatever is selected in the config) and not pulverized copper, so you have only one kind of copper dust and ingots to deal with.TE Recipe Hack, I don't know what this is, but it still interferes with Thermal Expansion, which is not IC2 related in anyway, and the difference has cause many flame wars.
Actually, TE is being deliberately obstructive here, since you have to go to TE's config and change a setting before it'll allow that to happen.
