The difference between 1 40 farm and 2 30 farms is low in regards to rainbow pack drop rate. So as a result, if you cannot farm lv 40, or do not get 7-8k points, it is better to do 30 assuming you can get 8k points nearly every farm. However, if you have the means, lvl 40 is the best to farm due to the time investment, since the "extra" .
