So, I have a *lot* of thoughts about the game so far, but I'm going to try to keep this to one issue.
Rogues are bad right now.
Sneak attack doesn't increase as you level up, which is a huge problem, and Expertise (the other most defining Rogue Ability) doesn't seem to exist at all. These are the only two problems I have at the moment, but they basically make the Rogue not worth using; my Dex 16 Elf Wizard with the Urchin background does everything I would want a Rogue to do and also IS A WIZARD. Also, this could be a bug, but Sneak Attack doesn't seem to work on Undead? Which is the old 3rd edition rules, but in 5E Sneak Attack is supposed to work on everything. To make matters worse, since both Disengaging (Jumping) and Hiding are bonus actions for everyone, Cunning Action can only be used for Dashing. Without Sneak Attack progression or Expertise, "I can Dash as a bonus action" isn't anywhere near attractive enough to make me want to play a Rogue. And that sucks because Rogue is my favourite class alongside Wizard.
On a positive note, I like the implementation of the Thief Archetype so far; Fast Hands equating to an extra bonus action and Second-Story Work reducing falling damage both make sense in the context of the game.
I would like to request that Rogues receive a much-needed fix, or that someone tell me something I'm missing that makes up for this enormous lack.
