I could make the greatest piece of content this game has ever seen, that would combine all players of all levels into a singular boss battle that consists of dpsers, healers and skillers as well as a few other uh, additions
this game has so much potential to go next level but lacks the creativity to make it happen, this boss would also have a special 1/1000000 drop which would keep the content extra fresh, all participating players would of course have a chance at the drop making it the single most popular event/boss to ever be added into Runescape since it's creation.
Other loot would be available as well, increasing each time in quantity as you carry it over from fight to fight, should you die you lose the stack, kind of like how enrage works with other bosses but without the enrage factor, just the increasing of loot and loss of loot on death, this cannot be a solo boss as you need wide variety of players to kill the boss, missing even one faction will result in failure, you could have leader rolls for experienced players whom wish to help newcomers much like how people help newcomers learn Croesus. This system could also yield additional rewards such as randomized clue caskets, this would be great for player engagement as well as player morale.
I didn't go too much into the actual idea just some of the general basics, good luck!

This is how streaking works, not enrage.
In case if you don't know, the RS3 team is actually considering making rewards stay the same regardless of the current streaks. Streaking will still be thing, but not for better loot and also no penalty on death during the streak. So no gambling factor.
