Ok, so here are the changes on S8:
guild war was: spectral. banshee, plague mogul, now it's pixie, dragon lady, doppelganger
coliseum was unicorgi, herald, brozerker, now it's trio, medusa, megataur
expedition was kraken, spider, aqua, now it's weredragon, catapult, bone
guild shop was crimson witch, revenant, dust devil, now it's magic dragon, moondrake, hydra
fight pit was shaman, cutie, shadow assassin, now it's slayer, water wyrm, rabid
You can see for yourself that none of the newer heroes are in shops, just like the last two months. Shall I tell you that this is the 4th consecutive day that has banshee as a soulchest hero and she's been a soulchest hero for 6 days out of 23 days?
