I know, and I like the Ninja Tower a lot!
And you are absolutely right, too many people complain about new features or content based on incomplete informations. Try the new content, if its not to your liking make some suggestions for changes. After some complains SG gave better rewards for completing NT. Thats a good example that feedback works. What never will work are rants about quitting if this feature will be implemented or that event will not be changed. I would like critics to be more constructive, and not everything new is a ridiculous money grab.
