Since we have yet to experience the new system, I see no merit in beating on this dead horse any more.
Yes there are those who like it and those that don't. I am on the fence until I have the game in hand, or we get an in depth explanation as to how it will work. An RPG doesn't need a set of arbitrary ability scores to define a character, and certainly doesn't need one where these scores increase as you level. Everyone could max out all of their abilities eventually, and this means every character has the potential to be identical to every other; super human demigods.
