Why I (STILL) love playing BFV and absolutely hate playing BF6

The major elephant in the room in my opinion is the super fast full health regen. It affects nearly every aspect from map design to TTK. It means you have to have fast TTK or else the enemy player can just run and get back to 100 health within seconds and also the same with map design - you can't just gradually whittle players health to zero in buildings or wherever as they constantly can reheal so you need the crazy multi points of attack in every flag/ building to flush people out.
