One attack in a thousand is enough for the game to not be worth playing for me.
And it's not about excitement. A Zoo visit could surely be made far more "exciting" by going through the monkey habitat while dodging whatever the monkeys fling, but that wouldn't make the visit any more enjoyable (or worth experiencing).
What is the difference between you dropping a hammer on your toe and someone intentionally hammering your toe? The end result is the same, isn't it?
Not from the start, no. But some time during development a lot of players thought it was a good idea, and Frontier was open to implementing it if that was what the players wanted.
But, if I remember correctly, more than a lot of players thought it a bad idea. Including most of the PvP players, and quite a few of the PvE ones (like myself).
Not just the intentions. The fact it is a player. I don't care if the player attacking me without my consent thinks it's better for the game, if he is polite and fully roleplays the whole encounter, or even if he is willing to stop when I make it clear that I don't enjoy what he is doing; I don't want the player attack to even happen to me in the first place.
This is why, in UO, convincing the suits that having griefers in the game was bad for business (despite them being paying customers) was very important for dealing with the issue. And the devs did so, in part, by tweaking their working definition for griefer: "A griefer is someone who, through his social actions, costs you more money than he gives you."
And, apparently, PvP in Dark Souls 3 is now more opt-in than it was ever before in the Souls series. Seems like it was remodeled after Bloodborne, where unless you intentionally use a specific item you can't get invaded at all. Which got those that want tostompPvP unsuspecting players with their knickers in a knot.
and for those people who do not ever want any type of PvP encounter to be possible for them, that is the whole intention of solo mode, even in mobius group there are circumstances where PvP is allowed in the group
