How a fleet of Infinity-class ships changes the Human-Covenant War

What if ten to twenty Infinity-class ships were available halfway through the Human-Covenant War?

The UNSC could form powerful hunting groups and defended hubs, inflict much heavier Covenant losses, and possibly accelerate political fractures within the Covenant.

Ten to twenty Infinity-class ships would bring both capital-ship firepower and carried frigates into the Human-Covenant War much earlier. The frigate complement is corrected during the exchange to ten per ship, giving a proposed twelve-ship hunting group 120 escorts. Smaller groups could protect threatened worlds, while concentrated attacks on a Prophet's command ship could damage Covenant prestige or encourage internal fractures. Covenant reserves and commitments across a much larger territory complicate the outcome. An immediate assault on High Charity is rejected as suicidal. A suggestion that defeat might force the Prophets to risk High Charity is challenged because it is too important and its artificial intelligence might refuse.
