I don't want this to come off as, "you're doing it wrong", but more of helpful advice. You're using flash way too many times and not using savage when you should be. You shouldn't even need to cast riot blade ever really. I don't even have it on my bars except for fates so I can spam flash for aoe credit to get max reward. steps 1 and 2 are fine, but you shouldn't waste provoke so early. The healer shouldn't even need to have cast anything yet and the dps should be giving you at least 5 seconds (I know dps...I know...omg 5 seconds, but that's forever). Step 3 should be the start of 2 or 3 skill hate combo depending if you have RoH yet. Fast blade doesn't even build hate other than just what you get from the damage. You need the combo to generate your huge amounts of threat. Just tab the combo through the group, minus slept targets of course, and you shouldn't need flash more than twice most of the time. This is all of course dependent of if you have smart dps that know what /assist is. If they are each attacking different targets, then good luck to them as I usually let them(mostly mages) get beat up on till they learn /assist.
I think you play with WAY better people than I do, lol. Point taken 100% on Provoke, I didn't really understand what it did until 1/2 through writing that. The reason I use RB instead of SB and RoH (I just got it this morning) is because I am finding that Flash is sticking my aggro just fine on the main targeted. To elaborate, let's call Flash as generating 100 Enmity (I don't know of a database that provides this value, so I am totally making things up currently), and then let's assume that the FB>SB>RoH combo yields 120 Enmity from SB and another 200 from RoH. Those are values I am guessing at after watching my extended aggro list in the bottom left corner during fights. If I cast flash 1 time for ever 1.75 other GCD abilities I use, I am generating roughly 22.85 Emnity per second per target via Flash. I am also generating hate via damage from RB and FB, and we will say that the melee dmg that I am doing is equal to 55% of the melee dmg that I would do with FB>SB>RoH.
Now, if we look at SB/RoH, its going to take me 7.5 seconds (2.5 FB, 2.5 SB, 2.5 RoH, repeat) to generate my 320 Enmity on a single target. That's 42.66 EPS on ONE target. If I need to spread that out over 3 targets, thats 14.22 EPS. Adjusting that upwards for my increased melee damage is tricky, but let's give SG and RoH the benefit of the doubt, and even though I don't think its likely, we'll say that they break even on total EPS on all mobs. (increase the # of mobs, and Flash takes the, extreme, advantage).
NOW to the crux of my argument, consistent Enmity generation that can compete with MRDs. If you are cycling through targets doing FB>SB>RoH, that means that with 3 mobs attacking your group, you are going to be leaving a single mob completely unattended for roughly 22 seconds depending on your skill speed. Let's say during that time the healer has to spam you because of a couple bad crit, the archer accidentally switches targets (or wasn't on the same one to start : D) and lays down a nasty string of crits, etc. Every second you are not attending that mob, your EPS on it is falling quickly, and the more likely it is that the mob will turn its attentions elsewhere, causing you to pop provoke, stop hitting the main target, and we all know how things can get messy from there, especially if you are level 32 grouping with level 36s. As long as your AE Flash EPS + the EPS from your FB>RB can hold aggro over the dps, this keeps a nice, even flow of Enmity on all targets, at an arguably quicker pace.
Now, would I use this strategy for an excellent group? No. Would I use it for a big boss battle? Obviously not. But in a situation where you need to rise above idiots and people who are struggling with targeting, that strategy can provide nice results.
Excuse my math and assumptions, if even if I am pretty far off (and I don't think I am), the point remains consistent. I just don't think you need to FB>SB>RoH to hold aggro over 99% of dps classes and healers, it is an unnecessarily large amount of aggro on a single target, and using it on multiple targets has serious flaws.
