There will be like 1-2 public events up at any given time in the world. Most of them are on a rotation where they happen multiple times per day, although we have plans for some that happen more rarely than that.
I mean, that’s why the World PvP is opt-in. We may designate some areas in the world as “safe zones” (such as the area directly adjacent to Highsteppe or areas around graveyards so you can’t get spawn-camped), but for the most part I’m seeing World PvP as a risky activity for any level of player that you can choose to opt-in to if you want that risk.
I also think if you are wanting a more “honorable” PvP experience, then that’s the niche Battlegrounds now fill. World PvP will likely continue to be fairly “cutthroat.”
There will be 4 dungeons available at launch which are matched content that you can queue up for at any level. These same 4 dungeons will then have shard-level versions available at launch that you can jump into (and which are not matched content). We anticipate the first raid coming out ~6 weeks post-launch as well.
