The 2012 only has 2 days now, so I think it is time to summary the favorite and hated updates from the year.
My favorite updates of 2012:
1. Player-Owned ports: This update is a high-level members minigame that was released on 11 December 2012, as announced in the December 2012 Behind the Scenes news post. Borrowing elements from the Managing Miscellania minigame, this minigame involves players building their own port in order to manage a fleet of ships, staffed by recruited crew members. These ships explore the Eastern Lands (otherwise known as the "Wushanko Isles" by the port Navigator) on the player's behalf and return with exotic items and supplies that are otherwise unavailable. Players can start by heading to Port Sarim. South-west of the Rusty Anchor pub is a portal that players can use to enter their port.
2. Evolution of Combat: it is a complete rework of RuneScape's combat system, released on 20 November 2012. Billed as "one of the largest content updates in RuneScape's history", the evolution brings a variety of new content including powerful abilities, dual weapon wielding, new Magic and Ranged equipment, and new Prayers. In addition, the combat triangle has been massively balanced, monsters have new attacks, and the combat level formula has been revised.
The worst updates of 2012
1. Squeal of Fortune: The Squeal of Fortune (also known as the SoF) is a daily activity available to both members and free players, initially introduced on 28 February 2012. Free players get one spin a day while members normally get two spins a day. The Squeal of Fortune resets every midnight UTC. Rewards include armour, weapons, xp lamps, coins, and an assortment of equipment, some as illustrious as Lucky equipment, the untradeable counterparts to powerful existing equipment.
2. Clan Avatars: The Clan Avatar is a members-only customisable reward available for clans. It was first announced in the 2012 August Behind the Scenes. The avatar is made out of elemental forces, providing boosts, buffs and protection to clan mates while summoned.
