When over-encumbered, you can dodge and move at full speed.
You, in fact, don’t roll at full speed. Why, yes, it does let you roll, but it is the slow, fat roll for being encumbered. Update the description or allow a player with the perk to still at least medium roll.
No you cannot dodge full speed, you don’t regenerate stamina as fast and you cannot charge speed attack while over encumbered. Which is absolutely correct .
