Monks in Guild wars and how to play it

Guild Wars Money is your energy for your life recovery. Every team needs monks, well, usually. Usually, balanced builds tend to run two core monks, not counting smiters or whatever. You are the team primary source of damage mitigation. Red bars will drop, and you will make them go up again. Generally speaking, there are two ways to mitigate damage - prevention and recovery, translated in game into prots (protection spells) and heals. Generally speaking, it is much more energy efficient to prevent than it is to recover. Throwing a prot spirit on a target before two warriors and a lightning orb falls on him is always going to cost less energy than healing all that damage over with orison. Prevention is very specialized, however, and will not work ALL the time. That is why damage recovery is always an important aspect of the game. Bottom line: make sure your monks got both prevention and recovery covered.
Pre-protting is a must. Watch where the enemy damage is focused and be there ahead of them. If you see two warriors converging on a target and you know they are going to release adren, do not wait for them to get there to start your protting. When there are warriors in play, try to keep a subconscious count of how much adren he has. If you have seen him train someone for half a minute without using an adren attack skill, then you know he is got a full tank of adren and is ready to release. That is when your finger should be twitching on that prot and watch carefully where he is going to end up releasing that adren.
Following that same line of thought, watching the enemy is going to be much more important than watching your own team.
