Remove the runner, crush its soul, rip it apart into pieces and throw the remains into the depths of hell where it shall not be able to escape the grasps of satan!
Woah there, jetmo
Anyways, I've been toying around with the idea of a sentry-like class, with about 150 health, slow speed like the overweight, and something like a heavy bolter or autocannon as the only weapon. The strategy would be to position yourself in a good place, then fire upon the boss dealing a good amount of damage. The deal with the weapons, though, makes the class vulnerable if found by the boss, as the weapons immobilize the user while being fired. Basically, it'd be the polar opposite of the runner: heavy damage, slow, and medium-high health, while still being weak if caught alone by the boss. Only, this won't be like a twisted version of duck hunt.
But, this class hasn't really been tested to see if it's OP, extremely weak, or above all, fun to play.
