Instancing is something that was always going to happen, as stated above.
I lost respect for Morph awhile back, when he had his tantrum about getting
bombed by A2's, lol. I enjoy his Architect Reviews however, but never cared
to watch any of his streams.
Without instancing, much of the content of the game will just be ignored by
many players, similar to what's happening already. Pyro content is a prime example.
Nothing like exploring some facility, killing off NPC's and looting some cool stuff as you go,
only to get executed inside somewhere or at the exit by a player who then teabags you and
tells you to get gud.
Sure you can respawn and rush back to try and get even, but not everyone wants this
kind of player adversarial gameplay. Especially all the time. Sometimes it's nice to just lose
yourself in the universe of SC and soak it all in. Take a few friends in, and have some fun.
(just be careful coming out of the instance, because if it is static, it will be camped) /shrug
