There needs to be more reason to get VIP vs playing F2P

+5-10% run speed (stacks with Genesis Runners and OtherShoes)

Give reach equivalent to a pet with 10 speed (stacks if you have a pet)

Daily reward in dashboard - 1000 coins

Weekly reward in dashboard - If you log in every day you get an untradeable energy consumable 420-1000ish energy

Monthly reward in dashboard - Mystery box that gives a random item (could be 99 stack of popberries could be T4 Mine)

Make crafting Tier 3/4/5 VIP only and create a marketplace buy back like the GE in OSRS does with mega rares(the best items in the game get bought with marketplace tax then burned to keep the prices high)
