No Asie. Buildcraft should have simply changed their EnergyAPI a bit and everyone would have supported it still..
The main reason why people left was because the API was simply: You have to do it our way and thats it...
If you wanted to make a converter you had to constantly drain the Energy out of the custom battery in the old system to make it work.
A simply IC2 API like thing: Receiver and Sender would have been enough... Switching to RF was the same solution but you got ride of what BC was worth for. Its own uniqe power system with Explosions...
You just described the RF API. MJ was unique because it had rules. It worked a certain way. It wasn't intended to be a universal power API, it was BC's power API. The explosions were never part of its identity, they were simply a failed experiment by cpw that I eventually removed.
