At first, each skill sounds different. Woodcutting is for RuneScape gold gathering wood, while firemaking is about making use of the wood cooking is to prepare food, et cetera. Each skill has its own meaning. This is not surprising. There is a commonality when we consider the training aspect. Repetition is the most effective way to learn the ability.
For leveling up attack, you don’t have to kill one monster. It is necessary to kill hundreds of monsters and possibly thousands. Although you could kill every type of monster, that would not be very effective. This is the case for any skill. It doesn't matter if you're cutting trees, mining ores, hunting salamanders, crafting runes, making summoning pouches, or smithing cannonballs; the training process is always about repetition. Running in RuneScape is more about repetition than your ability to think critically and develop skills for life. It's all about the length of time you're able to complete the task you're assigned for. This is what all existing skills have in common and what the new skill might avoid.
It brings me back a few years ago to something I shared with my friends at the time Bachelor Fridge first came out. Jagex was becoming too excited about games that involved strategy. This I discussed with my buddies. A lot of new FunOrb games are about strategy. Jagex has been incorporating this into his life for a long time.
While I don't think this new skill will be called "Strategy" however, I won't attempt to guess its name. But I believe that this skill could include a strategy element. People will no longer claim that RuneScape can be reduced to clicking and repeating. Strategies are a technique that can be utilized by itself and have an effect upon all other skills.
I'll explain one way this could be done. Since the new skill can benefit the existing skills, I believe it will be a part of the current skills that will have an option to plan your strategy or you could learn how to create and utilize new tools. As an example you can observe that certain tasks, such as mining and cooking, might have a Strategy On/Off button. This allows you to activate or disallow strategy mode.
The strategy mode will allow you to train the new skill and may increase the frequency of your product. It may also mean that you'll have access to recipes and formulas that will require a specific strategy to cook or produce.
The new skill cannot be repeated. It is likely that people will learn it quickly and be able to train the skill in their sleep. It is crucial to realize that the process of determining a strategy isn't easy. There are many factors involved: timing, randomness and situations. The player will have to adjust to the circumstances similar to cheap RS gold minigames like the Burgh de Rott ramble and Barbarian Assault.
