There are, in my opinion, three issues with datacrons (DC): 1. Some are hidden in hidden places. I follow a guide to get all the DC while leveling, so I won't have to go back and look for them later. How glad I am I did it. One of the DC was hidden in a zone, with entrance not visible on map. There was an elevator that had button bringing you to another level. I would never guessed where this was, even if looking all over the planet, in every hole there was, running up to places that were not intended to be reachable. This was really stupid idea, I doubt anyone found this DC by themselves. 2. Some are reachable by jumping. The jumping mechanic in this game is not good if goes to precision, and there would be no problem with it at all, if not for the fact, that we are required to use to jump very precisely to get to some DC. 3. This is the most stupid thing I ever seen when searching for DC. You have to sometimes wait for some flying object to pass you, so you can reach the DC location. These wait times are 20-40 minutes! What the hell, Bioware? You want us to stand in one spot for 30 minutes, waiting for stupid balloon to pass? Seriously... I found many, neatly placed DC while travelling. Some were visible from one spot, and you had to search for the entrance, some were just in some nicely hidden zones, that looked really climatic (especially the ones on Dromund Kass, i loved these in narrow passes), some were in some "jumpy" locations, but not involving too much skill, and the places were very clever. Some are just in such stupid places, you want to kill everyone responsible for this.
