Just to add to the DRG Fang and Claw/Wheeling Thrust discussion, when they were RNG in HW, many Dragoons didn't like it, especially when we were talking about extreme/savage fights. The main reason? You couldn't properly plan what you had to do. With only 2.5 seconds to see which one you had to use, then position properly, it just wasn't enough time, especially when you take into account boss movement along with other job mechanics. I'm pretty sure the reason it was changed in SB to guaranteed combos is because of the general dislike of the RNG.
