I've been playing without the tuner...
I haven't done a "compare and contrast", but I generally avoid them...
They're primarily designed for online play, which I assume means MUT or H2H, and that's not what I'm doing...
That tuner is the tuner that was dropped before the patch (as per Clint O. on twitter), so I figure it got folded into the big patch that followed anyway...
I'm also "fishing" on AP...much more promising, post patch...
