Darksiders 2 lock on system.

Hey gamers. Today I was playing Darksiders 2, and I realised that the lock on system is really annoying. I was in the most annoying boss fight-The Construct Hulk- And right when I was about to go in to hit the boss when he was down, it locked on to a minion! I'm not sure how they did the lock on system, but even when you use the mouse wheel to change targets it's rather annoying. Now, when you're just fighting minions or nosses (which is short for not bosses) the lock on system is fine, but boss fights just get annoying with the lock on system.
