Am optimistic about Halo 6 in some way, but there has to be some changes.
Improving the MM system big time, matching parties vs parties and less vs solo ,and low skill vs low skill.
If dedicated servers are still a thing they need to find a way to make it at least equal to everybody and not giving the advantage to whoever is near the server like in Halo 5.
The big ambition is Warzone 2. That's where most players will go. They need to really make it special this time. Adding more maps , modes and objectives is the key. Balancing the vehicles and reqs.
Find a way to get players busy and grinding ,and I don't mean something like Achilles armor, which in my opinion is the reasons why many stopped playing. You are locking something behind killings others, I mean come on, it had to be abused. Add the to that the horrible MM system full 12 man team against solo, what's the fun in being farmed? 4-5 matches like that and people will just lose interest.
So there has to be a way to let team vs team in the next entry without limiting the fireteam to 6 players, which also resulted in low player counts.( work on your MM system)
Warzone can be really huge in Halo 6 if executed in the right way.
Bring back all the popular game modes from previous Halos from day one.
Bring back the art style,
Remove clamber so you can make fun maps. Get Certain Affinity.
Get Marty back,
Bring back the Chief , not the one you have developed. Concentrate on him and fuck Osiris.
MLG
And maybe we can get the old glorious Halo days back.
