A minion build has way higher dps than a dps build.
If you can manage this build and stack plenty of health it works too ofcourse, and it'll be a lot easier getting kills with this build than with a minion build.
Did you know spirit weapon's extra damage is doubled whenever you control at least one spirit?
And it gives even more damage for every 3 spirits you control.
Mard's Hammer gives 40 damage but no attack rating, so at low lvl it's better than 5% rating and 15 damage, but I guess your item works better at the higher levels, don't know around what level that would be though, might as well be 15 wich makes Mard's Hammer better in most games.
Also, health gives way more benefits than dps.
BoTF = 800 health
Mard's Hammer = 40 damage
800 / 40 (let's say it's DPS, but it's actually quite a bit less till a higher lvl)
= 20 seconds, I don't see a lot of fights lasting this long
So you need to hit your enemy 20 seconds before you get the advantage by using a damage favor instead of a health favor. Wich makes the health favor better in nearly every fight.
Your guide is missing quite a few things too.
Do you use shield? Do you use Surge of Faith? Do you increase the Spirit Ward skill? ...
What items do you get after level 3?
