You have a Dieing game and it needs to change you are making the wrong choices when it comes to balance.

There is currently ONE winning combination A logistics suit (the very suit designed to Support all other suits and NOT push objectives on its own)
And The humble Assault rifle A high recoil weapon purpose built for mid range combat with high damage

But for some reason People have discovered that You can tank a Logi suit higher than Anything else on the field making everything else obsolete And combine this walking tank with 4 equipment slots with a turbo controller to completely negate the recoil and you now fill every role on the field

How do you fix this you may ask?

Strip the Logi suits down to 1 High and 1 Low slot thus forcing them and others to use other suits on the field at which point then have a purpose for the heavy scout and assault suits again.

Assault rifles. this is a different matter, Combined with a turbo controller it has no recoil, Write a bit of code that will lock up the rifle after the trigger is pulled a certain number of times in a second if it is over the allocated amount of pulls (or button pushes) = jam,

Add an overheat on all rifles to even further negate the turo users which will even out the playing field for EVERY OTHER PLAYER

I can see why you don't Change things that are broken, because 98% of the player base is exploiting the **** out of it and if you change it you will loose them, but if you don't change it you will never grow.

Just STOP LISTENING TO ALL THESE CHILDREN WHO WANT IT TO BE A COD Copy Paste YOU HAVE NEGLECTED YOUR ORIGINAL PLAYER BASE AND FOR THAT YOU ARE PAYING FOR IT
Remember all the Player run corporations that you first did the spotlight's on a long time ago? well they all quit this game for the same reason, NOTHING WAS BALANCED EVER the game isn't fun for the people who play fair.
