Just get stuck into moving your 2d workflow over to bleder. Its similar to other animation programs, it has a time line, a canvas, and a layer system, with imports, and placements and movements, and drawing capacity. Then its easy to buy effects from the blendermarket, and use them in your 2D, lol some of them are so cheap, its too much fun, and easy to buy them for a few bucks and create amazing effects, such as 3d flames or lasers. Gives your 2d animations the edge, and from there, you'll find it easy to transition fo 3D completely if you want.
