It lowers hp by 1925 ... which is a bit weird, but can totally work for barb when you reach over 5k hp.
Not sure what you mean by boring play style. Throwing axes around and stuff dying is boring ? Or kill speed is too low to go fast through mobs ? I haven't found that end game unique throw axe thus i use Beast rw. In this mod rws go in any item, so gamble a rare axe, punch sockets and make rw - profit. If you need high runes - do act 1 countess runs, tower levels are packed with unique mobs and give nice stuff plus good xp.
