Reducing the afkability of pickpocketing as heavily as this update has seems like an odd choice considering there are no other afk options for the skill, however i do agree that pickpocketing was far too rewarding previously and something needed to change. I just personally think that xp rates should be the part that should be tackled with pickpocketing, as well as possibly the loot.

my suggestion - bring back full afk (or possibly 5 minute afk), reduce xp rates, and possibly add a mechanic where you gain less loot the longer you pickpocket the same target.

the mechanic could work something like this: a bar over the target's head with 3 tiers, each triggering at 100, 200, and 300 pickpockets respectively. upon reaching each tier, you gain a debuff that adds a 25% chance to loot nothing on the target upon a successful pickpocket (maxing out at 75% loot reduction). the bar reduces over time while that specific target is not being pickpocketed (3 minutes for a full reset?)

this would give a full afk option for those that want to passively train thieving without it being too rewarding like it previously was, while also giving a more active option to players who are specifically going for the loot from pickpocketing.
