Didn't they announce that there would be no negative modifiers to attributes? I seem to recall that somewhere. If that is the case then can any stat be a dump stat? Ok so my character has an intelligence of 5. If I have a crappy GM who ignores roleplaying, then it sounds like I won't care if I have any attribute in the crapper. There must be some penalty to really low scores.
Str: No decreased chance to hit.
Con: HP don't factor in by level
Dex: No negative AC for bad dex.
Wis

idn't matter much anyways
Int: Not tied to skills anymore
Cha: No penalty to skills like diplomacy
