As a warlock, I personally don't care about this rivalry... To an extent. A warlock, a hunter, and a Titan in a fire team is essential to victory. Hunters, where would you be if the warlocks couldn't self revive and all the nightfalls were lost? Warlocks, where would you be if the hunters could not go invisible and revive you guys when you used a nova bomb or did not have your radiance...? It still is fun to watch (and contribute) to this fire fight though... ;)
