This is THE way, to get massive gold pre S3.
what to do :
Arena 3v3 teams 2000 rating sell for like hmm, 500g +.
1 )BUY ONE, just ask in trade that ya want to buy one.
now you got youre 2000 rating team, -> 930 points a week estimate.
500g loss because you bought the team.
2 ) tell in trade youre selling 900+ points a week for 300-500g.
trust me you get spammed by gold buyers, wanting there new S3 gear having 5k points when S3 starts.
3 ) invite 5 buyers, play the 10 matches get everyone 30%. most likely you wont win much but still you have like 900 points a week.
assuming you got atleast 400g per spot ( what i get ) you have round 2k gold a week. -500g team = 1500g.
4 ) Spam in trade for a new team you want to buy, lets say someone sells it agai for 500g, now just sell that like 1900 rating team from last week for a nice price and buy a new one and repeat.
5 ) Have fun being a cash money milionaire
Enjoy, use it, but dont leech the community.
