I have noticed that the buffs your character has on them when they log out affect the character when you choose the live feature. This can be very misleading when looking up someones character to determine their raid viability. For example, if you are looking for a tank with a large health pool, you might see that they have 50k health, and you would automatically figure rough estimates for raid buffs that would increase health. Now you are expecting a tank to have say, 75k health fully buffed in ICC for example. Then the said tank shows up and gets buffed and they only have 65-70k health fully buffed. This makes for a seriously misleading information pool.
