I don't think that it is a fine move from CG to treat us adults like 5-year-old children :wink:
Learning in life means to try and fail, and to learn from your mistakes. If you always have some weird "god" floating around you and yelling something like "don't do this!" or "you can't do that!" you will never know IF you are able to do it or not.
If a bunch of adults in one guild decide to try this TB they have to accept the "no rewards"-possibility, like it is with any heroic raid. If you try this for the first time, and fail, you wasted also a few days of raid rewardings. Don't see any difference here.
