This is actually near the top of a long list of the things I like; but then, Rogue is my favorite class, and I can tell you there's not much more frustrating than having your prime source of damage nullified in almost every fight (my DMs seem to love pitting us against Undead).The only big change I dont like is nearly everything that was immune to sneak attack now isnt.
I love Rogues too- many of my PCs (dating back to 1977) have at least some rogue or thief as part of their multiclass structure- but I hate this change with a passion.
