Plate tanks get to see there shield block % which is there minimum block Claims are made a brawlers Min block is raised incrementaly by a small percentage of there +block % items and directly by + min block chance items. We dont know this though because our number must be a national security risk as it is not listed in the persona window.
According to a conversation I had with timetravelling, basically nothing has changed for us with regards to minimum block since last expansion except the name and the tooltip dissapearing.
