@CarreraLuuHow often do you need a melee takedown? Most often it is much easier to shoot people. This is not a stealth game and melee rarely makes sense.
The number of times I am close enough to an enemy, my primary is already empty and I 'potatoed' my Glock and really have to resort to knifing I can count on one finger after 200 hours of BF2042 (and I would not need this finger as the count for me would be zero 😉 ).
In my book and given the state of the game the melee animations are not even ON the list of things to fix. If they were, they would rank FAR, FAR down.
