One really great and very simple pvp feature that DAoC had was kill spam - when you killed someone in RvR everyone in the same zone would see text in the general chat saying "player x has killed player y".

This was excellent because you then knew that there was pvp going on somewhere in the area, it sometimes gave you an idea of who else is around (like maybe someone you want to hunt down, or someone you fear), and some players got a very cool reputation for being able to get multiple kills.

And if you didn't like it you could always just turn it off.

I hope ESO has kill spam!

Why not? Especially if there is an option to turn it off and on....

So long as stealth kills don't show up.
