Warzone Ideas/Brainstorm

Hey guys so chasing some ideas/ feedback on the Warzone gametype. In talks with other avid halo fans and current H5 players and from what i gather players hold a love/hate relationship with it. Please keep it constructive.

So ill start off with the wraith and the scorpion i think 343 should bring back the older boarding style. This would mean having to melee the cockpit hatch off before planting a grenade. Also being able to melee the driver to the point of dieing and taking the vehicle for your team.
