Fixable problem about Halo 5: Guardians

Alright so I understand different people have different opinions but these are definite problems with the newest halo that need to be fixed

1: The Magnum, The weapon takes barely any skill to use and can out power the DMR it is a weapon that you spawn in with in almost every game type, but when you spawn in a game of Warzone or Breakout just look around you. Almost every player switches to their magnum because it is more effective than the primary weapon the assault rifle. The literal term used for pistols is a side arm. Side arms are last resort weapon. Try to imagine an elite Navy SEAL team drops behind enemy lines to take several objectives. But the first thing that these advanced soldier do is switch from there FN Scar’s to there Glock’s that scenario isn’t even plausible. I think that Halo 2 had a great pistol for the sole reason that it was weak enough you would not think to use it as a primary weapon but strong enough that if you ran out of ammo you could switch weapons and finish your damaged opponent with it. I believe to fix this problem everything but range should be nerfed Auto aim(Accuracy) and damage.

2: Spartan Thruster abilities: Thruster pack,Spartan Charge,Ground pound
First off I love that the thruster was in H5 it was all I used in H4 but it isn’t very useful like it should be it is a one burst thrust that takes to long to recharge I believe that the distance should be decreased by 35% but you should get two that would make precision duels more interesting
The Spartan charge is just a piece of s
* it just encourages unskilled players to rush with success. But I don’t use it and neither does anyone I know but I get that most people do, it literally ruins assassinations I should be able to turn it off. Not to mention the charge up time is like 1 second it should be at least like 3 or 4 seconds of sprinting STRAIGHT it is annoying that you can turn corners with it. I have even pulled a total 180 with it.
*Ground pound is a really neat feature, but it break the laws of physics because for some reason it can affect players who are in air. I have taken full damage from the GP even though I jumped and Thruster packed away. I really wish I could also turn this off because it messed up “Ninja’s” which is jumping over an opponent and assassinating or beating him down, now when I try to perform one I just freeze in air and the enemy player kills me.

3: Shield’s: Sprint Recharge,
*The fact that you have to stand still or have very limited movement for 5 seconds is kind of…lame, it ads nothing to the game but frustration it should be removed.

4: The Battle Rifle
I have always enjoyed the weapon and the only problem I have found is that it fires WAY to fast, by the time you even realize you are getting shot you’re dead. I just would like to see it fixed

That is it really thank you for your time.
