Finally caught up!
A few questions: what the heck was the (abandoned) "Transcendence" vote a while back ? And why did it disappear after the scouts interrupt ?
And what's the thing with multiform ? We have a teacher on hand in Kakara's mother as a trained Tien style user and we don't go to her for how to train and/or perfect multiform ? the technique seems well known, if somewhat rarely used, so why do we need to re-invent the wheel here ?
Also, (regular) Multiform is the perfect tool to master/endurance training Golden Oozaru while still under the Training Hall since it cuts your total power in half/third iirc.
note: being able to hit power level cap of SSJ in just a couple of actions makes it feel cheap, and severely limits/cheapens progress. Like Betarel said, once you hit the cap what's the point of continuing ? Hopefully SSJ2 (whenever we unlock it) will need a lot of time to cap out
Transcendence was the action to figure out machine sensing (since Dazarel, also the ability to apply the revelation behind the Genki Dama) for Kakara's ki sense on a more permanent basis, prior to the systemic revision away from action points altogether. I believe the players dropped it in favor of emergency training in preparation for Dazarel. Presently it, and essentially everything, is on hold during the approach to the Unsealing, but once that's done, the project
will be going back on the To-Do List.
Multiform is well-known and well-charted; the frequent (and just as frequently dropped) actions you see regarding it are an attempt at reinventing not the wheel, but
Perfect Multiform, the technique Cell used. Perfect Multiform allows one to maintain a full four clones with no power loss. Kakara can presently maintain three, splitting her power level among them, and if she levels up her skill to Exceptional, which is as high as one can go without an Elite+ breakthrough, she'll be able to maintain four. Doing so is now on the To-Do list as a Training Goal, and receives background progress rolls.
Multiform training does not appear to actually help with endurance training for transformations, which is incredibly vexing, as it would, as you note, otherwise be the perfect solution for further breakthroughs.
FPSSJ feeling cheap and like a yoke around your neck is actually deliberate. Centuries after Goku and Gohan, the Exiles have gotten the training process down to an exact science. They get to that cap with supreme ease...and then stop dead. So strong, and no more. To go higher courts near-certain death, at your own people's hands even if the Enemy doesn't come to do it. That conflict is a central one to a Lord or Lady's life, and muddling the IC/OOC line on that is a very deliberate choice on my part. There is more --
so much more -- to be done in this universe. FPSSJ, while it looks and feels impressive, is truly just the first step into a very deep pool...and you can't go any further. Thus far, and no further, with the view ahead clear as day.
