I don't think they will do this,since ninja's weaponskills are used to setup a skillchain then magic burst(that's why ninja has skillchain and magic burst bonus job traits). Your real damage comes from magic burst.
Even solo with trust; a ninja can easily triple magic burst for 50k damage each magic burst on apex,for a total of 120k damage and only cost 3 tools. 1 skillchain and 3 MB can 1 shot Apex mobs and that is with only trust support. A Monk does not have a way to do this much damage,even with their h2h weaponskill buff. If all you are doing is meleeing and weaponskilling; you are ignoring half of what makes ninja different from other jobs. In that case just upgrade the ambuscade sword and spam savage blade.
