Warzones 1-3 are outdate, the items do no have high value anymore.
Warzones 4-6 can give to your team a good profit but it's not so easy to do, you will need about 10 ppl people at least and it takes your time since you must kill the bosses twice to worth. If you start to kill the bosses 4PM you will need the whole team online again after 8PM to repeat and it's not everyone that can do every day. Ppl People from my guild use to do it twice a week and it's hard to find players, we are about 170 most activy.activity.
