Thanks for the discussion. Here are some responses:
~ Yes, spike damage is a weakness of Rogues and other dodge based builds. This is by design.
~ On the topic of Sneak Attack and the top content having undead and constructs; this doesn't prevent people from putting value into Holy Sword and other critical boosting abilities, so using this as an argument that Sneak Attack isn't valuable is less compelling to us.
~ Once we decide what to do with Momentum Attack we will be holding off on other changes until we see how these play on Lamannia.
