Luke does what he likes with Ultimates and may or may not act on our feedback.
I listen to and consider every bit of feedback I receive as a TO, but that doesn't mean I'll act on it. The truth is that while some feedback provided is good, it can also be bad, biased, uninformed, or simply out of line with the vision I have for an event. None of the decisions made on things like the areas raised in this discussion are made by accident. Everything is done for good reason, regardless of the transparency of that reason.
I don't like to get drawn into debates on many of these topics because there's not often a lot of value in it. Many take their hobby very seriously due to the time, money and effort they sink into it, and as a result become quite set in their views on certain topics. I keep as open a mind as possible, but I also have sufficient experience in running these kinds of events to know what works and what supports the end goal.
Without being rude - at the end of the day, if you don't like being at the "whim of a TO" - then step up and start running events yourself.
