I am unsure about this news.
On the one hand, it sounds good, in theory. On the other hand, if the modifiers are very low compared to the randomness of the d20, it seems like it will make the whole system extremely swingy. And, to be quite honest, I want a 10th level fighter or rogue to hit kobolds, goblins, and orcs significantly more often than a 1st level fighter or rogue.
One of the side effects of this philosophy are some really weird DCs for common tasks. Like, breaking out of manacles is DC 19 strength or DC 21 dexterity. It seems to me that everyone - even the puny wizard - can break them given a little time, no? Not that this is a game-breaker, it's just ... weird.
(also, I put up my own playtest report from last night ...)
