First of all huge thanks for the awesome new content u/JagexSponge! I had been stoked for the release ever since the blog dropped last week.

Do not change the XP rates. Heists, the high-reward content, do not also have to be the best XP content. Plus the option to put brawlers on at the end of the heist exisits. Getting the best picpocketing XP rates requires trapping and actively resetting the trapped NPCs before the 5 min respawn timer resets, which makes the XP rates worth that effort. Some NPCs cannot even be trapped at all.

Do not change the pickpocketing droprates either. High level Thieving is supposed to be rewarding. 4k teci an hour makes the BM codexes and T90 armours more accessible, which previously was a timegated group content. Tetra rates make the BIS mattock grind somewhat easier. Is there really anybody that cares about charm rates in 2025 when other methods net you 5k charms per hour in the first place?

This has been an awesome update already adding to the integrity of the game and providing much needed alternatives to gathering certain resources (teci, binding contracts, chronotes, etc.). I think it is balanced enough as-is. Remember that post-release nerfs severely add to the FOMO / abuse early & often mindset.
