I can't confirm RuneScape gold whether or not it's true, but Jagex continues to be around record dozens of occasions stating they don't place significant dev time into pre-poll content. They mostly flesh out the ideas and roadmap and get community input pre-poll. I'm pretty certain group ironman was declared at runefest 2017 and has been supposed to be published 6 weeks down the street at the latest. Idk why Jagex makes many empty promises every Runefest; it's like they make all these plans and when they get into the dev function they realize it's going to become a lot more work than they anticipated but they're afraid of being transparent with the community about it.

The over-promise and under-deliver since it gets people to buy the premier club each year, and once they have their money from that it's like they no longer give a fuck about the real updates. Jagex has the skilling contract frame laid out quite a while ago. For example, PoF contracts were inserted on the fly. It was only a ninja update that took a couple of days. The question is do they have better implementations than skilling contracts.

OSRS has multiple brand new training hotspots

PoF contracts came with 120 farming. And frankly, there's not a huge reason to do them unless you need trim. They're only great for reputation, and standing is actually only worth completing for completions sake. Meanwhile, OSRS was stuck with the exact same old same old way of construction training for 7 years before today.

Saying aquarium is not the exact same old method of training is very questionable. Additionally, by your logic of"brand new hotspot = new way of training" OSRS has numerous new training hotspots such as gnome chairs for EHP training. Is not Mahogony Homes with the exact same old way of coaching for OSRS too? It was. At least Aquarium brings out more ways of adding fishing into it. If you're taking a look at brand-new methods of building training, wait a couple of months before RS3 comes up with fresh brand Construction approaches in the style of Safecracking at cheap RS gold. It has just been revealed from the livestream ongoing currently.
