Note: somethings will sound inconsistent but could be used to create other ideas
Starting with some ideas for content there is a lot of content that gets used once and not again because of progression
Dominion tower its great fun especially after the intro being removed before each round but once you get the gloves you need, it becomes lost in the darkness as there is no use for it anymore although its cool.
1 : Put more things into dominion example glove combiner something that can combine all 3 gloves into tribrid once unlocked can be found with a low chance something cool to grind for.
2: Making one of the platforms like endurance/ climber into bossing each floor has a random boss from ELY make it like NMZ or something along those lines where you can imbue certain things like rings or unlock / skilling items for iron men/ or something simple like coffers earnt by points and keys.
Climber PVM Mode easy/medium/hard mode ranging from normal slayer and bosses depending on difficulty .
You will need Tribrid gear/potions/food/antifires/anti poisons and battle your way through the floors killing creatures on which ever mode you desire something for new players and old players basing this off the slayer tasks you can get really simplifies this idea. rewards could be simply enabling drops in the mode or giving points like normal dominion tower.
i wont get into rewards too much unless you ask for my input.
Runespan
Having an AFK zone NO EXP WASTE! for the people that stay online when they arent around for example making runespan into a AFK zone its pretty useless over here siphoning ungodly creatures in the depths of i dont know where but it has a cool concept i think small things like reworking the runespan shop a bit could make this possible along with a few tweaks for siphoning having an afk zone seems to work really well for a lot of servers it makes the game look bigger and a lot more active i guess it has some form of *law of attraction* i once helped with this idea for a server and it was a huge hit but it was a lot more in depth i mean we are all grinders who does not want to come back on later with some extra juice!.
