From patch note that you would miss it.

-Defeating an enemy of a higher rank than oneself now awards more skill and experience points, while defeating lower rank enemies yields less skill and experience points.
-Party bonuses have been adjusted to award larger amounts of skill and experience points based on party size.

So you can find party and grinding with some Yellow or Red Mobs then you can check Behest time with /clock.

Guildleves still give you good skill point, don't make it waste.
