I have to say, I really hate the idea of locking on targets. Its really irritating how you'll be running away from something to restore health/stamina/magicka or something, and an enemy swipes and hits you from like 5 miles away. You can also do the same thing with a melee weapon, just not as drastic. Its the same thing with bows or staves, you dont even have to aim. I kinda think that takes the fun out of being a player who attacks from far away.
Before you get me wrong, I think there should be a lock on type thing for abilities, otherwise it would literally just be impossible to properly hit enemies. I just think it isnt very realistic and is very annoying how theres a lock on for light or heavy attacks, for both enemies and players.
I think I'd prefer the collision based attacking, like they had in Skyrim. How does everyone else feel about this??
