I've read the guide now and with the exception of making Double Shot lvl 5 early instead of saving 2 SP to make Speed Wind 5 as soon as you're getting it(this is extemely nitpicky tbh) the guide is correct from what I've seen HE's do in combat. HH, the new skills don't change anything much except your target now is unable to pot for a certain period of time, which is very useful when combatting everything without a heal themselves.
