Teamwork:This one is a given in just about any MMO. With the variety of instances and 'rift quests' in the game it is absolutely essential to be useful to the group you're in. You're not useful and you're going to cop a lot of flack. No one likes wiping, and if it's your fault for generally being a shitty player, you're going to hear about if from the group, that is, of course, if you're still in the group and they haven't kicked your incompetent arse out. The game requires you to be able to operate in a group to be able to succeed, basically, and if you fail to learn this teamwork you can most likely expect countless lonely hours of grinding.

Time Management:This is arguably the most important thing of all when it comes to MMOs. When to do what and for how long? "Should I craft for an hour and minimise Aion and do some homework, oh waiting for that I'd need some materials, which means I'll have to grind those Balaur for about an hour or two. Of course it is, but still, I find myself now organising my time with my real-life commitments in the same way I would organise myself in Aion and you can too. Time is the same, no matter what you're doing and organising is absolutely vital to success. To succeed in Aion, organise yourself properly and stick to plans, to succeed in life, organise yourself properly and stick to plans!
