Ideas for next update, - Guns - Suggestions appreciated

I have two issues with TierV weapons. Here they are.

1. If TierV weapons were to be added, do you not understand how powerful they would have to be made? Barret is already almost 1 shot kill every time, so what would the TierV sniper have to be? Unless all the guns were reduced in damage so that they could fit in, however, I am sure not many people would be happy about that.
2. If TierV weapons were to be introduced, you would also have to add a new Tier of Armour. Just like Diamond armour can withstand TierIV weapons reasonably well, you would need a new armour which would withstand TierV weapons reasonably well as well, otherwise the game would just completely loose whatever balance it has

If you guys can compile these two ideas into whatever suggestions you come up with, and you think it is a reasonably good idea i.e It has a good possibility of being added, Tag me in it as I will be interested to read them.

 

We could remove some of the current guns, or replace some of the higher tier to lower tier and add a new gun. For example, the Tier IV automatic is the Ak-47. Well, perhaps we could remove that and add the M4A1 which may do less damage but shoots faster or some thing. I think if any of us want anything it would just be choices to customize and do as we want in WarZ. Say we didn't even remove the Ak-47, but added the M4 and they are both T4 weapons. Perhaps one is more accurate and shoots faster while the other does more damage. It's just a thought, but I think I would like to see some more customization introduced to WarZ.

 

Wouldn't look good, the current guns are tools and if they are items it won't look that good.

 

These could work for reasons above but this could work
