did you miss a chance to play w/ friends b/c you picked a shard and raised a character to 20+ w/o checking which shard they were on? dont reroll just yet. cryptic and perfect world are planning to collect the shards together a'la STO. if you have characters on different shards you will soon have both given access to the unified AH. friends and guildmates can see your "lost" characters from the other shard(s).
what does the megashard mean for you? what are you looking forward to?
