I personally doubt they'd make Paladins suddenly potent damage dealers - that does nothing to contribute to the identity that SE has been trying to puns of Paladins as the most defense-oriented tank out there. My guess is that we'll see a minor overhaul to the class, similar to what Warriors got in ARR to make them more viable as main tanks. What exactly they'll do is really anybody's best guess at this point, but we've got just over a week before we find out (and even less than that before we see the preliminary patch notes so we can get an idea).

At this point, I'm just glad they're listening.
