The underlying problem I see is the Rogue being able to double martial damage dice output with Sneak Attack. I'm not in the "Rogues should rampantly out-damage Fighters when they use Sneak Attack and do the same damage the rest of the time," camp. One of the reasons is that it leads to absurdities like 74 point non-critical sling-stone attacks.
That said, Solo monsters should not lend themselves to the otherwise quick-and-dirty fight meme of DNDNext. From my perspective it's OK for solos to be a little "grindy" in terms of HP and defenses since they don't take as much time moving around as 4-5 standard monsters would. Solo encounters should be less "swingy" than they are under the current iteration of the rules. Maybe that means more HP. Maybe that means damage resistance. I'm sure they'll come up with something, given feedback.
