It's important to differentiate between skills and attributes here.
Attributes should and do level extremely quickly, and you're able to completely max out your character in a single day of playing, or under an hour if you know what you're doing.
Skills however, currently have heavily boosted experience gains for the beta. You can reach 100 in basically any lore skill with a very small amount of materials.
This will obviously change, and I believe for the better. Having skills take a long time to reach level 100 makes them long term goals, and increases player investment and attachment to their character.
Take refining in MO1 for example. That skill took an extremely long time to get to 100, and gave very tangible rewards for doing so. All extractors will know what I mean when I say getting 100 refining was a day to remember.
