Honestly, I think a higher TTK would encourage more strategic thinking in players. The maps, in fact, are too small and with a low TTK, every minimal distraction is fatal, generally rewarding whoever shoots first regardless of the circumstances. Even in other discussions, references to COD are popping up, and in recent days I’ve seen several memes calling BF6 'Codfield'.
My fear is that in an attempt to recapture the chaotic feeling of previous installments or to attract the COD user base, the sandbox nature of Battlefield is being abandoned. Some warning signs for me are the size of the maps and the fact that currently they seem structured like corridors (See Cairo), greatly limiting player freedom.
I also add that, in my opinion, there are too few vehicles during matches.
