please tell me what arena ranks did you check, because i just checked the top 50 fighters of 2v2, 3v3 and 5v5 of lv19-20, lv21-22 and lv23-24
lv19-20 2v2 and 3v3 is owned by mcs, but in 5v5, there are only 7 mcs in the top 50
lv21-22 2v2 and 3v3 has around 30 elves and 20 mcs on the top 50, but in 5v5 i only see 15 mcs in the top 50
lv23-24 2v2 has 25 elves and 25 mcs in top 50, but 3v3 has only 14 mcs in the top 50, and 5v5 has only 16 mcs
it seems like the only brackets mcs control is 2v2 and 3v3 at lv19-20, guess you forgot to check lv21-22 and lv23-24 ranks since you are lv20, champ
here's a screenshot of the guild's rating top 10
Mcs won the first place 30 times, elves won it 41 times
Mcs won the second place 15 times, elves won it 32 times
Mcs won the third place 17 times, elves won it 22 times
nice "facts" you have
