I must admit, I never paid much attention to datacons in SWTOR. I knew they were a reward for exploration and I assumed they had some sort of title or cosmetic reward attached to them.
But after a little chatter in general chat, I found out that there's actually more to them than just a sense of achievement. They actually grant a permanent stat-increase to your character (+4 something, generally).
Now I'm a little torn on what to make of this. The idea of chasing around various planets for hours on end, trying to track these things down isn't exactly my personal idea of fun.
On the other hand I can understand Bioware wanting to reward explorers. I just don't know if this is the right way.
I know some people may say, "oh it's only optional, you don't have to do it". But then again, a couple of datacons can easily add up to the value of an epic item or two. Does that mean getting better gear is optional too.
Personally I'd just like to see an alternative way of attaining these bonuses. Something that's actually challenging, rather than just time-consuming.
