As a guy with a Shaman, Warrior, and DK at 80 I am aware of the difficulties in getting all of your alts geared up, and even tanks need someone to tank for their Mage, for instance. Without the ability to do a census and see what specs is being played most often by which tank capable classes, it is hard for me to know what is going on beyond an anecdotal level. Alison recently posted about which classes are getting invited to tank, and while it is an interesting subject I have to admit it does not seem to matter in my case, the second I log on to either of my tanking toons I am usually in an instance irritating mobs.
One of the hardest tasks when it comes to playing the online game is to find the necessary Anarchy gold in order to transform into new weapons. This task can become an easier one if you are aware that you can actually do their job in order to help you enrich your virtual characters with new weapons that are essential in order for them to survive on the battle field. You will have to carefully plan your entire game and you will also have to take into account the characteristic skills of your avatar players.
