You shouldn't be shapecrafting wood logs into planks when you can build a saw and get the normal amount of planks. MFR is your best bet for wood. An MFR only solution would have a large animal pen, feeding an upgraded sewer or sewers which would feed into a composter which would feed into a fertilizer which would increment growth on a sapling which would then be harvested by a harvester and the sapling replaced by a planter. Alternative multi-mod solutions include forgoing the planter and using stationary turtles to place carefully arranged saplings over a wide area handled by just a single upgrade harvester relying on numbers and area to overwhelm growth mechanics. Steve's carts can also be used as a mobile planter instead of turtles in conjunction with the harvester such that one does not need to use woodcutters at all much less repair them. I have not had success using steve's carts as a fertilizer, but again turtles are good for that if you want to put time into it. If not, relying on larger farms is the way to go.
Now, alternatively to all that if the problem is that you don't like that you'd need a saw to get 4 planks out of a log, this is completely configurable.
look in the "GregTech.cfg" file for this section:
general {
...
find this line:
B:WoodNeedsSawForCrafting=true
Change true to false. Once you do, you will get 5 planks out of one wood log when using a saw or 4 when shapecrafting just a log. You may also want to look into the DynamicConfig.cfg and enable storage block crafting/decrafting and disabling block smelting. This will allow you to enable fortune/auto smelt interaction in the TinkersWorkshop.txt without that exploit being present (although it will still warn of it).
Naturally if this isn't your server you'll have no control over these settings. But you could always relay them to the Admin as some server operators don't really delve into the configs before making a server live. It won't be necessary for users to touch their own configs unless the owner modifies block IDs.
