That's utter fucking bullshit. It's a ripoff. Case closed. They can say all what they want, it doesn't change the fact that HAVE online is a ripoff of Team Fortress 2.
Their blind elephant stance is a very unorthodox thing to say, given that we've seen some gameplay in the promotional trailer, and we can already judge for ourselves, "Alright, it's a TF2 ripoff in third person." No amount of persuasion from SKiMedia will fix ANYTHING.
My advice, start from scratch, build from the same third person squad based combat with action figures, but build on it with more inventive concepts. Not ripping off other games.
