Ok jokes aside. The client does not show the correct mappool for you. Your mappool consists of 13 maps. See the announcement on the forum for an accurate description.
Still, it is true that ladder maps in your bracket have some macro heavier maps and I get your frustration by that, if that is not your thing. Feedback is always welcome. Do you think most players in your rating bracket share that view? If so, which players do you have in mind? I try to assess what the general preferences are within each rating bracket and adept the pools to that. It is not at all obvious to me that your view on this is representative of the general opinion within the higher rating brackets. Although I do know that you are definitely not alone in this. We (the matchmaker team) recently did a trial in which we had 4 months of ladder pools without any macro heavy maps. There was no clear indication that players of the higher brackets enjoyed this more or less than the format before that included more of these maps.
Also about your last question, there is work being done on a veto system. It would be really nice if the developers get that to work.
