I asked my friend and this is what he said
There could be a bunch of reasons.
1. The MC catches a very high ranking Prophet.
2. Covenant Civil war.
3. Maybe they have more plans for Humans than just death.
4. Alien artifact that they do not know the location of. ( They can't risk bombing everything and destroying the artifact.)
5. Interference from another Alien race that doesn't agree with the Covenant.
6. Maybe their fleet gets decimated by us and they can't bomb, only invade. (Mc took out a large portion of their army in Halo: FS.)
7. Maybe they do still bomb it. That would pretty much end the War between the Covenant and the Humans. The MC might be just after revenge.
