What they realy need are builds for diffrent figjting styles
Why don't we wait and see if players actually embrace the idea of Expertise Dice for monks before asking them to design a whole heap of styles for them?
Remember... right now they're asking us to test the rules and whether ED help express this particular type of monk (a monk that Mearls specifically said was supposed to be an easy carry-over from the 3E version.) It's the 3E monk with 5E mechanics. And thus I don't think they care what our opinions are about it being "boring". They already know how people felt about the fluff of the 3E monk.
