I would rather see abilities, like RS gold dungeoneering which require skill (and possibly a strong team, which I believe is a fascinating and powerful concept), and to see these principles being applied to other areas. Agility would make for a much better experience and a lot more enjoyable gaming.
Although it won't necessarily make the game simpler but it will simplify the game and require less time. The game is easy enough as it is. The OSRS buy gold main thing is time. Make it more difficult but faster and you'll have an even better experience.
