after 3 days, I'd say overall season 3 was a good update.
The Good
Neither Chasm or Cliffhanger are balanced for competitive. this is actually a good thing. they are silly maps for social modes which the game needs. Chasm is like if Halo CE's Longest and Boarding Action had a baby.
Team gun game can be fun and often comes down to the wire due to how the weapon upgrades work.
The shroud screen pickup is fukkery, and despite not being a shield, def has its uses.
Oasis is a good map for BTB that finally gives vehicles more room to maneuver. Also has fixed vehicle spawns. I will say the rest of the game desperately needs this because random vehicle drops in big team is stupid as fukk and nobody likes it.
if ur an armor whore, Mirage looks nice and Spartanesque.
they added 3 new free coatings.
The not so good
There is still desync, still have wonky hammer physics with 21 ping.
while it was nice we got 3 new coatings, and armor cores, the coating and armor core system still sucks. compared to past Halos.
maps were taken out of rotation in BTB such as Fragmentation.
Dont care for the story shyt, although it had more effort than season 1 and 2 multi.
Customs Browser still feels buggy.
Still no Infection mode a year and a half after the games release! >
