When the amount of upgrades started to RS gold drop Jagex started doing upgrades to make things such as jar quest creation much easier claiming it'd let them release more quests again. That didn't happen because the problem is Jagex, not the difficulty of developing content.
This old chestnut mare has been ridden into the floor. Yes OSRS takes less to develop, but that's not and never was an excuse. You might not run like Usain Bolt, but I still expect you to be able to run a mile. Not trying is only a case of laziness regardless of the source. They just announced a new construction method from the fashion of size of Safecracking in the Q&A Livestream. I believe they also told us they're outsourcing and hiring a great deal of devs. Some are beginning as soon as next week, if MTX really matters then it is a fantastic cause for much more hiring.
Much like the coming storage upgrade OSRS is becoming to POHs
No point in having a bigger team if you can not get shit from the door. Dude it is such fun content too, I've done like 50 on my ironman and actually enjoyed it. Im half certain they had a lot of it devved before survey. Which honestly is rather problematic. I wish they'd do the majority of the work after the poll in order that they don't waste any work. Warding vietnam flashbacks hanging in.
Mahogany Homes was created in a closed environment by a single Jmod, once it passed on the surveys a group went to actually work on implementing it. When you have a look in Mahogany Homes it's really not a hell of a good deal of work behind it, just requiring a few new versions, apart from that it's reusing assets they have needed for awhile. Oh it was among the ones made on one of those free time idea days.
I believe they tend to work on stuff first if it's very likely to pass a poll or whenever they can use the resources elsewhere. In this case it was directly according to a popular proposal from 6 months ago so that they could guess it'd be well received. But then people complain they don't have sufficient details and vote it down. So they need to perform a significant amount of OSRS buy gold the work before bringing it to the poll.
