In Halo 6, I’d like to see alien counterparts (be it Promethean or Covenant) to all drivable UNSC vehicles, as they simply have too much power at the moment. In addition, the Spectre needs more weapon variants (analogous to the Gauss and Rocket Warthogs), for example, a Needler Machinegun or Plasma Battery (which could use either Plasma Caster or Launcher bolts). Furthermore, these weapons could be implemented as wieldable turrets, adding balance to the weapons sandbox of the two factions.
My Ideal Lineup:
Light: Gungoose - Ghost
Medium: Warthog - Spectre
Heavy: Scorpion - Wraith
Mech: Mantis - Grunt Goblin
Fighter: Wasp - Banshee
Gunship: Falcon - Phaeton
I know the Grunt Goblin isn’t currently operable by players, though I’m sure many of us would like it to be in H6. The Warthog has also been given WAY too much love in Halo 5, I thought the Sword Needler permutation would suit the Spectre far better.
These are my thoughts, let me hear yours!
