FFA Arenas- This is the least important thing in Runescape. The update brought with osrs buy gold an update that ended clan warfare forever. It was able to reduce the number and make the game more dull. I won't even get started about the dangerous arena. Ask for assistance. This happened after we couldn’t swap items for different ones. For low levels, air/law/etc runes and making armor.
Capped Trading- Straight forward, will probably be rendered ineffective if updates are implemented. Gravestones were created in order to make sure that individuals could not trade in the event of their death and also let them retrieve their possessions. DA tournaments- Was designed to restore staking, fails badly even after the updates. Revenants were designed to replace pkers. Many complain that they are too powerful. However, they're pathetic. They are too strong for f2p, however.
Evidence that Jagex does remove content... Old Bounty Hunter- Was one of the first methods of pking. A large crater was created from space, and it smashed every wild, old pking spots like the big bone, and the small bone yard were destroyed. # in your post in case you've have read this long.
Pvp games- They have decreased the number of pvp game worlds to two. DA tournaments - The old one was removed and replaced by some shizzlety crap which is equally ineffective. Things that got nullified after the updates. Player-owned shopsForums with a section that allows players to shop. These businesses have made lots of money and thrive. Running a rune-based business is a great method to earn money.
Duel Arena- Previously, this was a way to bet and win big. Trading- Self explanatory. Pking- Self explaining. Merchanting- Self explanitory. It's still possible, but it's just a mess. Hotspots for trading: Varrock, Falador, all five worlds, were always crowded in areas to trade various things.
I've been thinking of a way to train multiple skills to 99 buy gold rs at the same time make a great income from it, based on my experience. I'm thinking about setting a goal of alching 100k or more yew longbows from scratch and get 99 Woodcutting, Fletching, and Mage. It is my responsibility to acquire the following "supplies".
