Loki can be a team buster.But theres no prep and he constantly loses to thor with prep and thor is supes level.Pretty much everyone on T1 is mid-high herald.
Batman is peak human and then the rest on teams 2 are low-high herald.To me batman and aquaman can leave and JLA can still win but either way JLA wins.
Give team 1 one sided prep and they have a much bigger chance.
