It's not at all. Anyone spending 4 hours or more on that set of challenges, even if they hit the bug where no previous progress in them counted, I just can't see what they're doing, it's bizarre. The game is just telling you "go do these things that you do in the game anyway, explore the world a bit", but the way they communicated that was pretty crap, it could have been a lot slicker.
Put game on solo, pick up little side missions in Tarsis, go do them and have fun. An hour or so later you've got a load of the stuff crossed off without even trying... then go do a freeplay session and mop up... certainly not making pen and paper lists and ticking stuff off like some said, lol. The chests one is maybe the worst problem... but with endgame in its current state, you could argue it is getting you in the mood for GM3 chest farming runs tee hee.
