Oh noes! You snuck one by the radar! You smuggled a 1.3 suggestion onto the forums, and now the team has no choice! They have to design/develop/implement/test/release it!
Fusion has been suggested more times than the number of digits in pi... it's nothing new here. Not to mention you didn't even formally suggest it. You're better off drafting atleast a basic idea, as people have done before. From what's been mentioned every time someone brings fusion up, there isn't much hope for traditional fusion. You might see fusion characters someday (you can today if you download custom models), but no one knows for sure. Just gonna have to wait and see.
