>block the Warthog
One one hand Anniversary had a "scan" mode which could've been brought back as a little "tactical options" display to hint at little strategies OR some Mjolnir text OR Cortana lines could've done this. After all, are they just going to adjust the terrain for every vehicle blocker? Technically possible I suppose.
On the other hand I get wanting to "keep the fun going" by not blocking people, especially with how often people will have to get used to different shooting mechanics and still be doing so as of their first encounter with Hunters. Basically keep their morale higher than if they had to do some thinking/the intended thing of abandoning the Warthog for a bit. Let them jog their noggin' about getting around vehicle blocks in a new campaign after they're already fairly interested in Halo due to the CE remake. BUT I still think showing them a workaround is possible is even better than just clearing a path.
For me, back in 2009, I ended up thinking after my first run at the area: I know Elites will ambush me. What if I got 2 Warthogs and 2 Marines into this place for an NPC fight? Still, it's likely that just adjusting the terrain was quicker to do than any vocal/text/UI bit hinting at mechanics. It's undeniably a shame that Halo has fallen so low that such measures have to be taken at all.
