While this is mostly true, the 5E fighter mostly defends by PURE offense now. Do you really want to attack that Rogue standing there with a dagger who only does 1d4+4 points of damage on a non-sneak attack? Or are you going to going to take down the Fighter before he gets another 3 attacks against you for 2d6+4?
You're going to ignore the Fighter and kill the Wizard who can hit you with Save-or-Suck mojo, I imagine, and has no HP or AC to speak of. Especially as the Fighter also has a boatload of HP and AC - he's the primary CC target, more than ever.
