4545 hp / nano per minute if dual wielding, 3535-4040 hp / nano per minute if using a single weapon. Compare to Hack n Quack healing 2196 per minute and Notum Harvester giving 940 nano per minute. Really makes a trader a powerhouse.

5616 damage per minute if dual wielding, 4368-4992 damage per minute with a single weapon.

Great pvm, but can be horrible in pvp because of damage shields. Reflect shields will reduce the hp recovered, but wont affect the nano recovered.

taking your 30 hit/min x 25% for 2hander (well 7/8/7/8) seams correct but your dual wield damage should be higher, you calculated with 36 hits/min where you should be able to get 40 hits/min (1s attack + 1 sec attack +1 sec recharge on both) so dual wield damage should be 6240 and the HP/nano regain 5054, so even more usefull as perk. If you then go MA setup with say 2x sticks you get the 3d attack and by that 45 hits/min x 25% =11,25 (11/11/11/12) with the result of 6864-7488 DPS and a HP/nano regain of 5560-6065
