What kind of hunter charges a group headfirst knowing that he can't be taken down? you're comparing a hunter stalking a deer when in actuality it's equivalent to a Knife maniac chasing into a herd of Rhino's. Arc blade has damage resistance, if he's meant to chase people down and take them out, then remove the damage resistance, ala Predator, not make them an unstoppable killing machine for 10 seconds. Plus, you're completely missing the point that other classes have supers that can be easily negated (read - does nothing) by moving a few feet. Can't do that with a hunter, yet he's faster, can kill just as quick, can do it over a long period of time, and has damage resitance to boot.
