I've been silent on the issue of Gregtech for a long time, but I will not be anymore. In light of Greg adding code to crash the game, it has become a liability to FTB. There has been talk of other mods in FTB doing a similar thing regarding checking for a mod and if its present, crashing, but the mods that have those checks aren't included BY DEFAULT in a pack with the same mod that would cause a crash, as is the case with TiC and GT. It's an immature solution to a problem that wasn't a problem in the first place.
Honestly, I see no reason why he nerfed wood. Wood is not that valuable. Even in treefarms that are used to power boilers, most people I have seen are using a sawmill (TE) to cut the logs into wood, which completely bypasses the nerf in question. I honestly don't think MDiyo did anything wrong by circumventing Greg's nerf. I don't believe he changed any of Greg's code, but simply did what Greg himself does regarding numerous other mods. Now if he had changed Greg's code, that would be a different story. Greg's reasoning for nerfing wood simply holds no water.
On to my next point, I don't think Greg realizes that this nerf has a ripple effect not only on Vanilla, not only on his mod, but on other mods that have absolutely nothing to do with Gregtech or IC2, for example, TiC. To make the patterns in TiC you need two sticks and two planks for one pattern. One non-nerfed log would give you four planks. You then take two planks and get four sticks. That gives you one pattern and two sticks left over. One nerfed log gives you two planks, you then need another log to get two planks which gets created into two sticks (which I heard he also nerfed, but may not be true. So for one pattern, you need one log +2 leftover sticks vs. two logs (+2 sticks extra if that stick nerf is untrue). That's a significant change for early game TiC. That's only one example of that ripple effect, there's way too many for anyone to ever list.
I think the 1 log -> 4 planks is the one Minecraft mechanic that should never be changed due to a single mod, at least in a modpack, because of the huge domino effect and indirect "nerfs" it causes for other mods. Imo, no single mod has a right to do that.
