Based on the info panel, Criticals only double weapon damage dice. This is completely incorrect and makes no sense. Crits are supposed to double ALL damage dice. Rogues sneak attack crit hitting is supposed to feel amazing. If you do it with a dagger in this game, then you net yourself an extra d4 of damage. Woo.
Crit success and Crit fail on skill checks are decidedly NOT an 5e. Maybe a thing in older versions but not in Fifth Edition.
While I'm on the subject of Rogues and Skill checks, where the hell is my expertise? Rogues get kinda slapped around identity wise in this game, whereas Wizards rose to godhood thru it. Like, copying ANY scroll from ANY skill book? Yo dawg. Thats dumb.
Anyone using scrolls tho.... I guess thats something I can kinda live with. Still, thats a Thief subclass feature. So another Rogue thing that get taken from them.
