Bring back counter knife and boost transport chopper health

So I've been playing battlefield for awhile since bad company but in battlefield 4 I remember loving the feeling of counter knife 🔪 when someone came up to take your tags it was a 50/50 chance if you got it right I feel like they should bring that back in the new update and the transport chopper is too easy to get shot down. in battlefield 4 the transport could take 3-4 hit before it went down i feel they need to raise the health on it or give it faster cool down on flairs as it gets targeted by stinger AA and attack chopper at the same time if not multiple angles please take this into consideration
