The TTK is too short. Whatever you both say is just coping hard. You are probably loving it because it makes easy to get kills for you. Well because it is. If ttk is longer you actually have to have a good aim to hit someone for longer than 0.2 sec. Specially a moving target. The faster the TTK is the less skill it takes to kill someone.
A longer TTK would actually slow down the game a bit and it would not be all this run and gun mess.
Go try out gauntlet and you will see the TTK is night and day. Literally feels like playing a way better game. That is why I would like a bit longer TTK in multiplayer as well.
