By those screenshots, it's looking like the knowledge trees are still going to have a ton of unlock-grind associated with them. Here's to hoping all the professions are properly balanced in how to obtain knowledge points, and that catch-up is actually considered this time. Seeing the extreme differences between how the trees are distributed during DF was jarring; it currently takes way too long to get the required points to completely max out all trees, especially if you're running alts in through content a bit later on in the expac's run time.
I agree with the catch-up mechanism. The small amounts of KP granted by the books on gaining Valdrakken Rep, and from the Barter Bricks/Boulders in Zaralek Caverns, was nowhere near enough a boost. Particularly if you missed out on the treasure knowledge digs. These boosted some players significantly, but then the drop-rate was capped before the rest of the player base could take advantage of it.The key players make the majority of their profit at the start of the expac, so there's no reason why those with limited play-time should be penalised throughout an entire expansion.
