The marines and other forces that should fight for the WG at the end of the manga are dropping like flies, this doesn't bode too well for the final conflict where we should see Imu having more limited means that he should have at its disposal with the remaining forces being beaten without too much writing and lots of questionnable decisions, nor them showing their true battle potential, many marines and CP agents who will deflect or be sacrificed and other plot-induced stupid decisions by Imu and the remaining Gorosei and leaders under his leadership, but then again anticlimatic battles against the antagonists are the norm now.
