..Does, nobody else not care for that map?
It looks awkward to navigate: Jump, jump, jump, jump..uhhh, jump.
If any kind of rage weapon is included, it will turn right away into a sniping/camp fest. Hardly a test of overall combat.
You need a map with all kinds of terrain so that players can fight in areas that make them have to react differently. The winner of this tournament will be seen as "The guy who can fight good on uneven cubescape" not "The best fighter on Blockland".
