Yes, but this machine was put in to manipulate uu matter as a liquid. If they didn't make uu matter a liquid, the machine would not have been put in.no, but it does add machine to utilize UU matter in crafting and increases it`s energy cost, which`s been done in IC2 as well.
Besides, ic2 needed new stuff. Don't get me wrong, I started with ic2 back in tekkit and loved it. But now... There's nothing new and it's just gone boring.
Look on the Jenkins changelog. Tell me where you see a non-API/bug fix/typo fix by Greg, and this argument will be over.
