Hopefully it will not work like in brawls when somebody block the Chaos Legion-Summoner and you are in a Chaos-Legion-Only fray and have no other choice than to fleh.
OK I understand that now it get better as you have Riftwatcher summnoner and also second Chaos Legion Summoner, but I had already the case where I must fleh in a brawl cause only earth was available and the enemy guild has blocked the chaos earth-summoner - What a cool playing experience.
