1. blameF wanting to play the roles that made jks look like a world class player
2. blameF's anchoring is too passive on the maps he does play anchor on
3. poizon is really inconsistent
4. RUSH underperforming in his albeit difficult roles
4 might not be the biggest problem, but you can fix it by just getting a better player who can play similar roles. and es3tag has proven that on astralis.
