I just see it as a dumb tactic. I think it's lame to try a strategy where you have to die to win. Is it an exploit? That's for the devs to decide. To call something an exploit, I think it has to fall under the description of taking advantage of an unintended game mechanic. Is total hate reset in a primal fight due to a wipe an intended game mechanic or an unintended one? Unless they read minds, I don't think anyone here but a forum mod can answer that.
