Mini-Games
The lack of people playing mini-games triggers me, mini-games brought a lot of fun to the server and I hate to see them die out. My suggestion is to add worth while rewards to our current mini-games (Make them untradeable) or even add a new refreshing mini game that can breathe new life to the server. (I'm down for some soul wars) give players a reason to go play them, because honestly I don't see myself playing the current mini-games with their current rewards. Hell, throw some old school rares in there but make them cost a lot of tickets where players have to spend days/months/years playing in order to buy them. (Players with old school rares, please no hate)
Staff Hosted Events
I know that this depends on the availability of the staff team, but I would really like to see them hosted maybe 3 times a week? I really enjoyed the event divison hosted, got many members playing castle wars (Fucking miracle) Honestly a lot of people would play castle wars/pest control if double tickets were to be enabled. (It's sad, but the truth must be told) I'm also down for like duel arena tournaments, hide n seek, and much more! Also, don't be shy to host forum related events.
New Players
I speak for everyone when i say, I see a lot of new players in grand exchange simply begging to everyone for cash/items. I believe the reason is because not that they're lazy, but it's their lack of knowledge on how to get cash/items and 9 out of 10 times when they ask noob questions, everyone ignores them or simply make fun of them. How to fix this problem you ask? I believe someone said that there was a "Help" cc where all new players go in by default to ask questions... hell i'm down to join that cc and answer their questions while i'm skilling. (Rune crafting is boring af)
Duel Arena
I've noticed a lot of players lose their bank due to staking in duel arena and that's how the end up begging for cash/items at G.E. There's only one solution i can think of that can really help and it's as simple as removing staking from duel arena and keep it for fun dueling only.
Lending Item feature
I know that this got shot down before, but I really believe lending items to new players can help them progress in the game much quicker, and will eventually keep them in the server. At this point, I feel like new players are ignored and I bet they feel the same way. Of course these items will always be protected and won't disappear upon death and members can't enter the wilderness with lent items. (Let's make it where we can only lend maybe 3 items for a max of 24 hours)
I'll let you know if any more ideas come up, good job on the recent updates.
