Why do you want the fence parallel to the miter slot and the table aligned to the blade? Because you can use the fence and the miterslot to build all sorts of jigs to do incredible things with the bandsaw. Or you can buy a fence with drift adjustment or align the fence to the blade and use it for ripping and resawing, likely hamstringing the capabilities of the tool.
Watch Michael Fortune with all of his jigs and you will see how to use a bandsaw in ways that create productivity and repeatability in your work.
