Whom do you mean? The char shown by me is 2 Cleric/ 8 Bard/ 2 Paladin, so there are only two feats available. That does mean to take two times the increase of Dexterity, up to 20. Important for hit chance, initiative, AC (the armor shown is actually the medium Armor of Agility, 17 AC + the whole Dex modifier, just transmogged to a different appearance) and to a lesser degree damage increase.
As Crimsonrider's char has 22 Dex, I bet she also took two times Dex increase to 20. To start with 17 Dex and taking Athlet one time would also be possible, but that would be bad for the Wisdom attribute.
