Outdated Raids

[BillyKaplan]

You take a ready code from Trials Roulette and copy it. You replace all trials instance IDs with 6 raids instance IDs. Rename second copy to Raid Roulette. Attach that code as another entry in Duty Roulette menu.
Done.

1. "You take a ready code from Trials Roulette and copy it" and hopefully get fired for your horrible practices.
2. That depends heavily on how it was implemented. What you described refers to an ideal implementation of the system (making the relevant code generic, and easily accessible, for starters) which is not guaranteed.
3. That would still require development time and then, more importantly, testing.

Yeah it's not new content that needs to be checked from scratch but it still takes time and we have no idea where it stands in their priority list.
