Acceleration. An entire ability that takes a proc from 50% to 100% seems like a waste. Compared to Sharpcast which can take a proc chance from 3% to 100%.

Add to Acceleration the benefit of allowing Verholy or Verflare to be used without first needing to perform the melee combo. Similar to True North in that it removes prerequisites from ability use, and adds a decision point to the ability. This would allow RDM to use their capstone ability in more situations.
