Overall the replacements are not faster. There are smaller jumps in the amount by which the blinds go up, but the jumps now occur at more frequent intervals. They should still take approximately the same time amount of time to complete as they used to with the previous structure. Stars have standardised the buyins and rake across their entire SNG offerning.
There is already plenty of discussion on this in threads in both MTTc and Internet Poker.
OK, I stand corrected, the replacement structure does seem to be faster than the previous one.
But airing your grievances here will achieve much less than doing so in the threads which I mentioned. Stars reps are reading and responding to both threads.
You should also email their support about your views. Stars have reversed changes in the past, in response to negative feedback about those changes, and it is not inconceivable that they will do so in this case, if a sufficient number of customers complain.
