Lol, yeah, I guess, but I was thinking more of "I just finished killing this Elite, now I gotta go run over to this Gru-HOLY CRAP!"
In Halo 2, the one level I remember the drop pods (Delta Halo), you were sitting there, no enemies, nowhere to go, and then the ODSTs drop in. Of course, by the end of the level, they were all dead (I like to use them as bullet sponges myself, while I run away from the Covenant, works, but they barely make it to the Hunters, where they might actually be useful).
