Current descriptions sound like adventure zones will be open areas with high level group content. Do you want these encounters instanced?

With ESO's loot system, it isn't really necessary. If your 12 man group goes in and a solo player "tags along", would that bother you?

Should these zones be instanced so there aren't zergs of 20 solo players just zerging bosses? Should adventure zones be only for coordinated groups?

Personally I like coordinated groups. The tactics and strategy are fun. But other times I don't want to deal with a bunch of other people and just want to casually farm cool loot.

Your thoughts?

I don't know if the specifics for these have been released yet, pretty sure they havn't. But I don't want to see giant bosses with 1 million health and lots if people hammering its feet for 20 mins.
Maybe some parts be instances and some open world, but I want to see varying events, waves of enemies that offer a true challenge and proper coordination, something different than the standard rubbish most MMOs spew out.

I'm positive that Adventure Zones are going to be instanced. They haven't released if they will be or not, but I can almost guarantee it since they are their "raids" and raids are instanced.

Yep and they've now said that "raid" groups will be 12. You don't set a number like that if the content is public and open to just anyone running in and zerging it.

I'd say it would be for the best if they are instanced, for the end-game PvE community's sake. Though I honestly don't care either way.

Depends on definition of "instanced". In megaserver environment everything is going to be instanced and its only matter of scale

We dont know any details. In early concept devs were talking about small group encounters and some large bosses that need groups to team up to overcome. That hints multiple groups in an area.
