At this point what you are talking about isn't something that can be quantified. As I have stated numerous times, these games are very clearly not intended to be perfectly balanced offerings. If you can manage to CC down npcs and find a way to do it then great, more power to you. There are plenty of situations currently in the game where that specific solution will not comprehensively solve a combat and that would be the only thing I consider to be a problem in a game designed to be so volatile. A one size fits all solution is bad, finding a way to manage specific situations isn't even if that situation is common.
Except I can do it through 60%+ of the EA easily. I can do it to the boss easily. This is without me actually attempting to break the game with it too
It most assuradly approaches a one size fits all. If it's wasn't such a prolific problem I wouldn't be calling it a problem. You say the situation is simply common, if that situation is 75%+ of encounters than the devs have failed at the stated goal of consistent difficulty and the problem is common enough to be nearly one size fits all. At this point it's very uncommon to run into a situation where the above problem doesn't come into play.
It should be the other way around.
Nobody appreciates it when a game can be broken with one tactic. Goes back to the same reasons people are discussing why the warrior needs work cause it kills everything to easily and why the elf racial skill makes every other one moot
