Boost CFS Weapons

Hello everyone,

I remember playing in 2010 and 2011 online tournament on ESL, and the weapon variant was much bigger than now.. There were players playing with Ak-47, there were players playing with M4A1, others with SG552, others with AUG, there were even players playing K2 and XM8..

At the moment in competitive, and in online tournaments, there is only AK-47, and AWM...

This why? Because the AK-47 is the only GP weapon that takes 100HP headshot..
Lately we have seen several players playing with M4A1-CFS, the reason for this is because it has more wallbang than the other weapons allowed...
Since the AK-47 is the only one that takes 100HP on the head, the M4A1 is the one with the most wallbang, why not give some boost to other weapons?

My suggestion is:

SG552-CFS and AUG A1-CFS - Take 100HP on the head, but only when the player shoots with zoom, resuming: only kills if you use to zoom.

There isn't any SMG that is good in Competitive CF.. what do you think about increasing the damage of the P90-CFS or MP5-CFS a little more? It would be a good choice for various teams and players.
