So after some sleep on the subject, I think a lot of the points being made about how to get the most out of this mechanic are dead on right, but wanted to bring up (or agree) with a few things in particular:
1. Hover Shot is massive. We're not talking about some ability we just charge up for use on a WS. Every offensive action we take gets pumped up as long as we "do the dance". This will show its greatest benefit in longer fights, of which we don't have tons these days, but enough to where this greatly solidifies RNG as a great option for those moments...and RNGs getting to act like RNGs.
2. The RMEAs who have attached WSs that do NOT scale with TP just got the single largest boost I've ever seen given out in game. Gandiva, Armageddon, and Annihilator all have boosts to their white damage that we've been building around for years, but there is no direct benefit to saving TP as Jishnu's Radiance, Wildire, and Coronach all do not scale with TP. Recently some scenarios have arisen where WS'ing with those kind of options can be a DPS hindrance (like doubleshot and AM3 up with Arma against some mobs)....but this addition allows us to scale up damage on those 3 WSs unlike any other job in the game- we get to break the math of those WSs and how they were designed.
3. The inability for Hover Shot and Decoy Shot to interact will take some getting used to. As many pointed out, hate management these days is the biggest tool a RNG has for sustained damage in a long fight, and we have great tools to do so. But the draw of Hover Shot's DPS potential may cause some RNGs to ignore their other tools of hate management in lieu of big numbers.
4. All the +True Shot gear we have received in the past 3 years now has a lot more value. I'm interested in messing around with weirdo builds for long fights where these mechanics can be fully abused, and I think True Shot will be something to consider rather than "well, I guess that's nice the 1 time out of 1000 I shoot at that distance". We may need to sturdy up in order to stand/strafe/hover at that distance rather than always shooting from 20.4'.
All in all, its a LOT more than I expected. Major thanks to all who did the real work vs just getting to brainstorm on it^^
