1) Do bolter rounds now have the "Tearing" quality?
2) When you fail a non-combat roll, can you re-roll and try again but at a higher difficulty?
(and the biggie!)
3) What the hell is up with the investigation rules?! OK, you roll at a Challenging difficulty which is a 72 hour time frame. You fail the roll by 5 degrees and the task now takes 1 month and is at a -20. You fail again...and again...and again, adding 1-10 hours as you go. You finally succeed and drop the now 1 month and 23 hour time frame by *gasp* ONE HOUR!!! Yippee! Are you with me? Good. Now, you fail again by 5 degrees it takes 1 to 5 YEARS to complete your search! All for Snippy the Snitch who's probably dead anyway by now.
So, when, by the God-Emperor's grace, I actually succeed, by the rules I'm expected to whittle-down 1 or more YEARS 1 to ten hours at a time? WHAT THE ****?!!!
This needs some serious errata!
