The reasoning they gave back then was that they wanted the players to figure it out as a community. They still do that with a lot of things in the game today ("communicate with your fellow players to learn how to progress"), so it's likely still the same reasoning.
They also do it because they want to limit game-breaking things being discovered. FFXI for example, the great TP nerf dealing with asuran fists with relic knuckles. Due to how h2h damage was calculated, this was a 34 damage weapon that gave 20 tp per fist, with 2 attacks per round. After getting tp (2-3 attack rounds, or an icarus wing), they would need to land 5/8 hits (62.5% accuracy) to get 100% tp. Since it was a 34 damage weapon, mnks could still do ~800 dmg with asuran fists, and then have tp to do it again, and again, and again, without ever stopping.

Now imagine if people had stats to crunch together. It could result in some unintended OPness. People mentioned that WoW shows such stats and I remember a fuss over Hunters stacking shaman gear/stats (?) and having a ridiculous arcane arrow.
