This is the role's own baseline, winning a bit over half its games with steady eco scaling and sea trades roughly matching losses.
- + Team wins slightly over half of games played.
- + Metal production scales from ~4k to ~29.5k by 15:00.
- − Own metal lost climbs to 6875 by 15:00, matching kills closely.
- − T2 factory only reached in 40% of games, limiting late power.
