Quote from KdLoLcheck out the combination strike build that i m using
u gain 16% from using FoT and WothF, then 15% attack speed from WothF rune, so in this build, u constantly swich between Fot and wothf to maximze ur dps, breadth of heaven is no longer needed as u get more dps and loh + attack speed
I've tried using combination strike before and it always feels extremely clunky and ends with more deaths than if I hadn't used it. The build you posted seems like you're getting the same damage output/healing(if you have good LoH, I suppose) but with much more unnecessary complexity, which will inevitably lead to a "brain fart" death from not being able to pay attention to other things. Not to mention losing Breath of Heaven in favor of LoH heals leaves you without an "oh crap" ability if you're low on HP and there isn't a viable attackable monster for you to leech from. In addition to that, you're forced to use a passive on combination strike to reach the same level of DPS that breath of heaven would give, when you could have used it to gain more survivability or utility.
As fun as combination strike looks on paper it's just so overwhelmingly underwhelming I don't see a point to using it over a more streamlined build. Not trying to be a dick or a downer just saying, heh.
