eah, if by broke you mean "revived and made useful and popular again"
seriously, how many people used BC power in 1.2.5? I'd be willing to bet that most people were using power converters to power their quarry with IC2 power. Then TE comes along and suddenly MJ is the shit! and now that TE has abandoned it, it once again IS shit.
Actually, I used MJ quite extensively in 1.2.5. Most of it was generated via Biogas Generators or Peat-Fired Engines, but it was necessary to run all of your Forestry farm setups. At a minimum, I set up a Peat Bog/Turbary, Arboretum/Logger (with occasionally a Treetap if I was automating sticky resin), and generally a Farm/Combine + the addon that let me use Crops with the Combine (with stickreeds for a much better way to automate sticky resin).
Then I used Teleport Pipes to move the Biofuel to the Biogas Engines running the Quarry.
Then Multiblock Farms came out and... well... yea.
The MJ API is a nightmare. Basically, Sengir and CJ got so bleedin' tired of people screwing it up, that they made it 'idiot proof', which only restricted what you could and couldn't do with it. And declined to hear any constructive criticism on the topic. So RF came out. Now everyone is abandoning ship because RF is easier to use, more versatile and flexible, less laggy, and in general a better system to use.
With the way RF handles itself, and how engines auto-throttle... and how Itemducts are so intelligent... I have zero use for gates. And with zero use for gates, I have zero use for the Assembly Table and Lasers.
In the next version of ShneekeyCraft, I am -strongly- considering removing BC, Forestry, and Railcraft from my mod pack. The only thing I use from Forestry anymore is the Backpacks, and the only thing in Railcraft that I use are the actual tracks themselves. I can't remember the last time I used anything from the actual mod BC other than the wrench. Between Mekanism, Minefactory Reloaded, and Thermal Expansion 3, all my tech needs are pretty much satisfied. Just throw in a backpack mod and call it a day.
Yea, I'll miss the Railcraft tracks, particularly boarding tracks and such, but I suppose I'll just have to do without, because there's no point in installing such an enormous mod for one little part. Boilers have nerfed themselves into obsolescence, and with that, every other machine in the mod which works on the steam or power mechanic is of zero use. Besides, why bother building horribly expensive multiblock monstrosities when I have Mekanism Factories?
