FWIW, It doesn't seem super naggy about it's F2P nature either.
Now, even after saying that, I picked it up to look at with a few friends, but, it's not doing a lot to entice me or pull me in. Now, of course, some of that can easily be blamed on me. I'm very jaded by MMOs and easily see through most mechanics as 'time-sink' or some other bullshit, and very few games have elements in them dedicated to providing fun. Somewhere along the way (in my opinion) MMOs became more about how much skinner box can they fit into boring ass tasks and how long can they con the player into doing them. Especially when you're tackling any of these games solo.
Don't know what would finally entice me exactly, but, haven't found it yet.
That said, I did murderhobo my way through quite a number of things in ESO. It's frankly just more convenient than bothering with anything else half the time. I also did appreciate one guy that followed me around and begged me not to kill the NPCs as they hadn't done anything to me.
I simply replied with 'Lulz, phat lewts' and became everything I hate in the world.
