My question is this, that's how many people that have played that kit at least one time, correct? How, then do you know how many are actually playing that kit currently? You also have to take into consideration that more people that gravitate towards assault play more infantry oriented maps or modes.
In CQL the assault player is at a major disadvantage. Not only do you have to deal with infantry you have to avoid vehicles. All other classes have unique ways in dealing with vehicles. The M320 will make a slight dent to light vehicles and very negligible to heavy armor. The only advantage assault had was anti-infantry and assisting the team with heals and revives. Tying a core game mechanic to a mechanic that most people dislike or disagree with is a terrible design decision. Instead of attempting to have an organic move, you have a developer that decided he didn't like what some people played and made the move to something even more controversial. Instead of taking the feedback and suggestions from the community, he shoved it down our throats. He then makes a reply a month later and says "we know we nerfed it too much and support is a 'God' class, however, this time we will properly test in the CTE."
