Cheaters and OP helis and TTK

Hi,

If Im haviong a good game I might get a kd of say betwen 1 and 2, a bad game where no hit reg and hit behind cover etc can be as low as 0.2.

I often see people in teams with kds of 5, 6, 7 and higher. I know that some are snipers but some are not, are they really not cheating with a kd that high?

I see them very match, is this just cheaters in every match despite what ea says about its anti cheat system?

Also i see heli pilots with kills of 50, 60, 70 to 0. They are almost impossible to down. This is really unbalanced? A good heli player on a side is often the most likely to be the cause of a win. What do you think? Should they be nerfed?

TTK is really low, I can spawn and get killed instantly many times in a row. Its not very enjoyable. Often an enemy is camping why dont ea stop it.

Thanks
