An average group can still run WP 4 times an hour where they can only do AK 3 times an hour, 120 myth both ways and AK has much much more trash and even using the sacpulling method u cant speed it up much more than 20 minutes. SO for regular people it doesnt matter which one you do

Good groups can down WP 5 times an hour, making this 30 tomes an hour FASTER than a good groups AK (and an extra 100 philo), the next best option for philo btw is CM, which good groups can do a little more than 3 times an hour, WP is clearly the better options for the better groups.

CM farms are still top option for spiritbinding, but you get some done in WP and WP has more other rewards, so I expect the number of groups doing this to drop a lot
There is zero point in doing prae now except for variety if your just philo farming

In any case, we have more options now which is good, later we get more dungeons down the road too
