Make them indestructible and exactly the same as halo CE
Yea I wouldnt mind, and since everyone can spawn with plasma nades and pistol… vehicles are suicide atm. Or at least if they were H2 style.
The only vehicle worth the time is the Gauss hog and MAYBE the Mantis; anything else is just asking for a quick death.
Can we make everything like CE? 
If they made it a separate gametype with different damage settings and no personal Loadouts ALONGSIDE Infinity Slayer then that’d be cool.
Allow each side to have the same vehicle spawned near their spawning point. Like Exile for example: The starting point of one team gets the Scorpion, mongooses, warthogs, ghost, or if you are lucky the banshee. the other team gets a gauss hog, mongooses, regular warthog, and most likely the banshee. It makes it so unfair, why not do what they do in Ragnarok where each team has the same vehicles as the other team at each base.
They should add some vehicles too like the Falcon or the Hornet, I miss the UNSC aerial vehicles.
The Halo: CE vehicles were like floating bricks. Just remove turret overheat and buff the vehicle health a tiny bit.
