Very odd/strange online experience

Hi to any reading, since launch to present I’ve been experiencing very strange online performance from me as an individual that include: 1. A noticably slower rate of shield recharge time then any other player every match. 2. A very strange inconsistency in every single guns shot registration. 3. Watching shots from enemy team completely miss me and still deal damage as if they hit me in real-time. 4. My game engine that’s built in seems to be very slowed ONLINE (bots/custom game I’m un-effected) but online I.E. (Spartan sprint speed, slide speed, assassinations not being registered) And a few other things. I have good connection to game and solid frames. Every game I’m around 15-20MS. Not desyncing. I strongly feel it’s not an internet/graphics issue. Seems mechanical but I notice nobody else online are experiencing what I’m going through it’s almost as if I’m cursed/ strange voodoo every single match. It’s very strange and seems to be on a mechanical level. Is there anything I can do on my end? Maybe somebody can list some internet protocols to further better the communication if it is lagg that must be turned on to play? Again I’m voiding out lag because I DO NOT desync and play hours straight at 15-20ms. But if the numbers I’m seeing are true why are these above problems re-accuring every single game ONLINE and not desync’d or what appears visually of me not being desync’d online? All tips/feedback are appreciated and I thank you for taking the time to read this and help my further experience in-game online be a better one.
