They could gladly remove followers. But they wont. And followers influence in fights are not that big. I rather see people learn how to PVP than rely on mechanics that in other genres is counted as cheating. Becuase like I said, there is a few weapons you need to have a good aim with. 2h-Hammer, 2h-sword for example you just need to kinda have your camera directed to them, not even that in some situations.
No autolock is lazyness. A player that been training and spend alot of hours getting good with aim and such should never be owned by a noobie that is using an builded in auto aim mechanic.
