They are basically cutting content intended for the base game and then drip feeding it to us under the illusion that they're giving free stuff. It was bad enough in the past with withheld content being sold as DLC but now they are holding to ransom content we've essentially already paid for. 3 more maps are supposed to arrive for season one but we don't know if that's 3 gunfight ones, 3 6v6 or 3 ground war - it may even be one map for each mode. Embarrassingly shit either way.
Treyarch will probably blame the pandemic but even on a 3 year cycle with BO4, they couldn't even concoct a campaign, 60% of the game was recycled form the BO3 SDK and the MP and zombies was unsupported and on life support after Christmas.
It kinda puts into perspective how well IW supported MW post-launch - they gave us new maps in every mode and the game was content-laden in the end on top of Warzone. Treyarch have seemingly removed 6 scorestreaks too...
