Insta-Deaths Damage does not equal 100

Summary for devs:

I have a good ping most of the time, under 30ms for LAT, no Packet Loss was observed, TN does sometimes exceed LAT which is concerning. ALAT is always higher than LAT, between 40-90 traditionally. 

A. Enemy killing me/damage to me:

1. Enemy damage does not register on the damage log and a lot of my deaths do not equal 100 on damage log. 

2. The Enemy that killed me does not show on the damage log at all, but I die from them, listed in kill log at top of screen, kill cam follows them afterwards, but no entry in damage log

3. It feels like enemy hits are being bundled, where I die instantly with audio that sounds like all the shots came in bunch (think K30 RoF but for all weapons). 

4. High RoF weapons and 1SK weapons are the worst (shotguns, MM Rifles, High RoF SMGs, LMGs, and ARs)

5. The extension of this is getting killed way behind cover, sometimes 10 meters behind a wall or structure.

B. Me killing/shoot at enemy:

1. On the other side, up to 25% of my client hits do not register at the server, so it takes me an entire clip to kill one player.

2. The higher the RoF the more server misses there are on the log.

3. This makes the TTK and TTD seem way off as I am shooting rubber bullets and no matter what weapon they have, I die almost instantly.
