This is directed at Anet, but it would be nice to hear others opinions. The recent guild missions blog post states that guild challenges and puzzles will be instanced in HoT.
I know that my guild really likes to join up with other guilds for challenge and puzzles. Will we still be able to do multiple guild runs of these missions?
how about everyone else, do you like to run with other guilds, or hot join, or do you prefer to start all missions by yourselves?
