The problem is that the hunters are very weak and their supers do not do a huge radius of damage like a fist of nova bomb. That's the main problem. So not "Invalid"

Sure but what's the average kill amount for nova or foh,1,maybe 2? What about ward of dawn? Lel 0. Average for blade dancer? 2-3. Every now and then 4+. Golden gun is pretty much 3 kills every time unless you're a moron and activate it in the middle of nowhere. The health and damage reduction doesn't change because they can move while in the super,titans and Warlock super lasts a total of 1 second which is why they get a larger armor buff but even then it maybe doubles so if there is at least 2 people shooting at the person there's a good chance to,kill them and deny them kills.

I was on my level 4 Titan (At the time) and I got a 5 man. If people cannot do better than a level 4 with their super at higher levels then they are just not good. Also you can get more kills with Fist and nova if you are smart and use them at the right time.
