DC/BF was used twice, it just only shows once because the logger was phased out when the second set was used, still missing one use over the fight though. The same applies to the potions. A pre-pot was used but it never shows in the buff frames unless a second potion is used AND the logger is not phased out when the use of the second pot occurs. The logger was phased out here. Two pots were used during the fight.
This is why I really prefer it when people log themselves instead of relying on others to do it.
The reck falls a bit outside the use of the pre-pot, try using DC earlier if you go for an early reck so you can fit the reck in. This is in addition to what Grumash said about saving it for the Execute phase.
MS/OP use looks good. Slam does indeed look low. (P.S. you were really not lucky with crits in this parse!)
To confirm what Grumash said about HL. Only one Heroic Leap was used when CS was on the target, save it until CS is there.
