Have you think that you get full tier 2 even tier 3 within one month when you are just level 60? How? Please check it out below:

There are countless "Gold PuG" raids that take place each day... even for the veryend game instances such as Naxx or AQ 40. These "Gold Teams" are made up of usually about 20 or 25 experienced raiders that take along some noobs to gain gold and gear. No vent or online speaking software is used. The raids work this way: after each boss, players bid for the items that drop (starting at 100g for example for tier 2 sets) and people can go on increasing their bids till the others drop. Then at the end of the raid, all the gold is SPLIT UP BETWEEN ALL THE MEMBERS OF THE RAID. This can easily get you 300g per run. I've had some runs where I've gained 1k gold because people would bid 8000 gold on Ashkandi for example :D. This system is very different, and caused people to rush through content, and that is quite a pity. Another one of my friends managed to collect all his tier 2 gear and some tier 3 within 2 and a half weeks of hitting 60... However it allows people to earn gold to combat the HUGE inflations that occur in WoW China.
