-Give bonds a use other than skilling outfits and membership. For example blood money, double exp, droprate boosts, (comment if uhave more suggestions)

-Trading Post/Player owned Shops/Grand exchange for hardcores. Very hard for new people to get hold of stuff

-Godwars cave in wildy for ecumentical keys

-Combining clue easy, medium, hard and elite clues for master clues (check my bank for stack alex )

-Private bossrooms in places like Cave Kraken that doesnt cost charge of row. Currently only one person can kill kraken boss at a time because
there's only one room. Make an instance any time you enter for a gp fee or something if main room is taken.

-Update boss slayer shop. It is very bad for hardcores.

-Lower master clue cost in boss slayer shop.

-Explain better to new players that dont chose HCIM that its a mode where the exp rate is lowered and people can trade. There's alot of
questions about it
-Lower rareshop prices @ duel arena
