As already mentioned, Gamehag has no shortage of articles about Minecraft. With varying quality, I believe. Users and moderators alike might have grown sick of it.

Of course, the only way to get a detailed answer would probably be to try and contact Misty. No telling how long it will take for the moderators to answer, though. But usually it isn't possible to contact them directly.

It depends. If one were to be successful with game tasks or did the most high earning tasks on offer walls, probably the ones involving mobile games, one would definitely get the most of soul gems.

But even then, doing the tasks would require some time and work, not to mention the offer wall tasks might sometimes be a bit unreliable with their rewards. Also, I get the impression the mobile game tasks must be completed successfully within a certain number of days, usually a week or so. Failure to do so means you'll get nothing, so I advice thinking carefully and checking your schedule before trying any of those.

I'm not sure the promo chests are really worth that much. Can take a lot of work to get the soul gems required to unlock them, only for the reward to usually be nothing more than a random Steam key, which is usually one of the cheapest games on Steam.

I believe Kabash, one of the moderators, made a percentage counter someplace on the forums about the odds of getting something from the chests. All I remember is the odds of getting anything worth working for are practically nonexistent.
