RDM QoL change: Impact should overwrite the Jolt II hotkey when it procs.

[Shurrikhan]

You could use a macro.

/macroicon "Jolt II"
/ac "Impact" <t>
/ac "Jolt" <t>

That casts Impact if available, otherwise Jolt, which becomes automatically Jolt II after you get the level lvl 62 trait. Or you could also use Impact for macroicon, if you need a more visual clue when it's available.

And for this you lose the ability to queue, and Impact will typically be skipped over, straight to Jolt, if within a minimum wait period (1 second) of a previous command.
