It's more of the RNG of the RPPM trinket, since the trinket can proc like 4 times in a row, even on pull it can double proc in a row with recklesness, so with luck it's awesome for Arms AoE And single target due to "unlimited" slam spam, while the 10s proc and 55s icd is better for fury and the aligned stormbolt bursts. Basically you just got more uptime with the RPPM trinket and due to stable Arms dps you can get more gains on the crit trinket.
