I am one of the "lazy" players you speak of as many of the datacrons are in locations that I simply do not have the skills to get to.
I am only level 28 and I have already had to give several datacrons a pass as they are located in places where you have to have "Super Meat Boy" platforming skills to reach. I don't mind a bit of a "challenge" but I don't have the hand/eye coordination or timing to play "fighting games" like Street Fighter let alone make precision jumps that are required to reach several of the datacrons.
If I'm paying for a game I demand a "reasonable" opportunity to experience all the available content. Out of the way locations, okay, big monsters in the way, fine, even needing two or more players to gain access, its pushing it but fine, but I have to draw the line where you need to make several precision jumps reach it.
I have a question for the developers. How may players actually collect the datacrons. I don't mean a few, but all of them. If there are datacrons that very few of the players get then it is in a very bad location.
Remember, what is "challenging" for a small minority of players is all but impossible for the majority.
