So I like some of your ideas (like Dragonfire Dive sharing a CD with spineshatter) but a lot of them I feel are unnecessary or could be solved in different ways. Life Surge is also used on your first Wheeling Thrust and every 120 second buff burst, and personally that feels good to have more than just one thing to use it on IMO. But I do like the idea it’s a skill you can like pre-pull pop.
Also, your suggestion for an elusive jump that fires you forward is redundant because you can save a charge of spineshatter for that. What I’d do personally is make DFD and SSD the same skill and one upgrade into the other (DFD being the preferred end goal). This would, of course, have an increased potency to compensate. And your point of the jumps not being gapclosers is somewhat true except for the fact that they added charges to them the same they did for Cops-a-Corps for RDM. Holding a charge for damage buffs is optimal, but if it brings you closer to the boss faster it’s even better. Just because they do damage doesn’t mean you shouldn’t hold them for optimal times to get back in faster.
Your ideas to combine battle lit and Dragonsight I both like and dislike. I do believe DS needs reworked but removing it, in my opinion, removes some identity. Perhaps the idea to make them AOE. However I do think since they share a CD making it AOE OR reducing its cooldown to 60 and changing its damage buff both just raise the questions at that point “why have a separate button for Lit or Lance Charge. So I’m mixed on my feelings there. As for the “dragon partner” idea, I completely disagree. Because that’s no different than setting a macro for one, but not having a second one for if your partner is down/if they aren’t optimal. And as it stands optimal dancer doesn’t stick to one target the entire fight. They tend to bounce from whoever does the most during bursts to whoever does the most sustained damage outside of bursts. Which DRG isn’t too different from, as if my comp was BLM, BRD, RPR Id give to the BLM for the opener and the RPR for their bursts because they burst a lot harder than BLM after the opener if they’re using their two Communio burst as they should. Just an example. But if the RPR dies the BRD would be more optimal.
However I think the key ideas you said about mirage dive and Geiskogul could be said about WWT. Having WWT is nice and all but what if instead of it being gained from Raiden Thrust/the AOE version it just becomes WWT instead of Raiden? While yes it’s a gain to do it in buffed windows it’s also kind of a pain to weave it in bursts.
As for your geiskogul and nastrond and high jump and mirage dive, I’d like to expand on those a bit. Instead of just combining High Jump and Mirage Dive, High Jump also instantly charges for Life of the Dragon (and maybe take a hit to CD NA dincrease damage ETC). Make Geiskogul just get replaced with Nastrond when it’s fully charged for Life and increase its damage. No need to have extra animations delaying OGCDs. I’m mixed on whether I would keep Stardiver or not.
I’m honestly surprised you haven’t pointed out that without ridiculous SKS your Chaos Thrust will never last to the next one which feels clunky as hell. Just extend it to there come on.
And finally, to finally trim down on one less OGCD, I’d just trim Lance charge. Yeah I know that removes some of the distinction but I personally would make it combine with DS as I suggested earlier no matter the change to DS.
