Why Can't We Charge Weapons?

Is it just me, or should Halo 5 have the ability to recharge the weapons that use energy? Whether it be with a special charging station similar to the REQ stations, or just using another weapon with energy. I personally think it should be both. With the Charging Station, you could keep recharging your weapon, but it would cost 1 REQ level more than the cost of the weapon spawn, but you wouldn’t need to have to use a REQ card. With the weapon reloading, if it’s the same weapon, it gives the amount of energy that it contains, but if it is a different weapon with energy, it would give an amount of energy related to the value of the weapon and the energy left (It would also be cool to have an animation where you put both barrels together and siphon the energy from one). Considering the uses of the energy weapons such as the Plasma Pistol or Storm Rifle, being able to only use the amount of energy it starts with, it feels like a waste to have to use your REQ cards every time you want to take it out. I hope to see this in a future update, feel free to give your opinions.
