As a monk, this was one of the most frustrating aspects of playing with people in groups.After a major battle, the monk's energy (as well as other caster classes) is usually empty and recharging. If someone (such as a warrior for example) runs to the next group of enemies and starts taking damage with guild wars gold, the monk can't heal them without energy! Since none of us are mind-readers, it's also the Monk's (or other caster's) responsibility to send a message informing the group "I'm recharging-please wait." If they persist in doing stupid things, and you've asked them not to, and you started the group, kick 'em out of the group for more guild wars gold. Perhaps they'll learn something about making guild wars gold.

An example: Skills that deal holy damage are VERY important for a monk if you're going on a mission with lots of un-dead, (skills that deal holy damage do double damage against un-dead).Check your skills before leaving for a mission.This sounds obvious, but once you leave a city, you're stuck with the skills you have in your skill bar.Since skills can change depending on the mission, what you built last guild wars gold mission may not be appropriate for the current mission, and it's going to be very annoying if you ask the guy whose group you joined if you can start the mission over because you forgot to equip the proper skills. And, if you're a monk, did you forget to equip resurrect? Not good.

Admittedly, a warrior can take damage like no other class and can probably take whatever he jumps into, but what happens when the 8 Charr beating on him suddenly head for the casters in the group who are still building energy to cast spells?Wait for your casters to recharge. Nothing is less fun than everyone blaming everyone else for the last battle going badly. There's some intelligent people out there who are ready to explode all over someone else because things didn't go right.Even if someone does something absolutely stupid, geez, give 'em a break-perhaps this is the first time they've played with a group, perhaps they got caught up in the moment and didn't think. Regardless, say "Hey, please don't do that again-it's getting us killed".
