this strategy is good if you have a lot of SECs if you use it with low number of SECs it will cost you a lot of peros because you will encounter normal EG too much . I used it in the previous EG event with 2R & 2N SECs with 3M~4M peros spent on elixirs my over all SEGs killed was 1600~1700 can't remember exactly . 1000~1300 kills were through support the remaining I found myself .
