This is situational so I keep roh combo as my dual button so I don't use it. I also have fof tied into SB and cos, sw and ms tied to roh. For bosses you don't have to silence or are OT this gives a long buff that can be extended with shield swipes. This leaves all your big buffs for later so I rely a lot on my healers with this combo, I let them heal me out and try and save my big buffs for when I really need them
