Thanks for all your hard work,

So. Perception skill. I think it's worthwhile to get Perceptiveness to where it needs to be to generate a second advanced skill. Intensive Focus(IF) is, as the name describes, a skill designed around deliberately narrowing one's focus on specific objects of attention. For a number of reasons, I feel this does not best meet our needs.
1. Ling Qi's combat paradigm is heavily focused around groups, crowd control, and support(buff/debuff mix). This role isn't best-served by a perception skill that trades away awareness of the broader conflict when used to its full potential, since broad-scale changes are her own focus of impact on the battlefield. Keeping broad awareness of the fight at the forefront of her attention is especially important with arts like SNR, which has a perfect defense than can shield allies, but only in a limited area around Ling Qi. Understanding everything that's happening on the battlefield mostly-equally is vital in deciding where to deploy techniques like that to best effect.
2. As a scout, one of Ling Qi's main duties is to search out enemy forces or other kinds of threat. However, danger can take a very wide variety of forms, and a scout is looking over wide areas at a time. Thematically, a skill that leans itself to focusing on specific things won't shine brightest in this role. She can focus on the task of searching for danger, but full use of the skill won't engage without something more concrete to work from. Intensive Focus is well-aligned with the scrying in RME, but the scrying is ill-suited for scouting or exploration given its limitations.
3. Ling Qi's build isn't good at using IF in combat. She has relatively few techniques that can decisively take advantage of specific details or vulnerabilities she might discover about a single opponent using Intensive Focus. Almost all of Ling Qi's techniques are AoE and thematically aren't great at, say, breaking through a weak point in an enemy's armor. FSS's CtE is a potent single-target attack, but that attack requires setup and basically doesn't care about what flaws or weaknesses an enemy has, given its potency. It's difficult to argue that Ling Qi has the tools necessary to leverage IF's best qualities in combat.
4. For utility, Intensive Focus is at its best with things like cracking Formations or tracking an enemy, but these skills haven't been rewarding or used very much at all. It's also solid with scrying, but the limits of our scrying technique make it very unlikely to ever be used in opposition to interfering effects. Thematically, it would make sense for IF to help with things like studying Academics or Government,
however those also aren't things that it should be necessary to have a B+ rank Perceptiveness skill to effectively study in the first place. Intensive Focus suffers from Ling Qi rarely making use of skills it is best suited to boost and/or not mechanically
benefiting from the skill. Fluff benefits don't need the skill to be developed any further than it already is, honestly.
IF isn't a bad skill, and Ling Qi's character is richer for having it, but it's not the
best for Ling Qi's adopted combat role and the things it
is best at don't come up enough, and aren't likely to, to be ideal.
Instead, it makes sense to get another skill, something with a "bigger picture" focus to match where she's putting her efforts and needs to pay attention in a fight. Something related to how she was picking up on enemy death-screams from beyond the physical, or the Shishigui's war drums would seem appropriate and fitting with her character.
In min-max-y terms, a perception skill with that flavor would also be a lot more likely to fuse with Empathy when one or the other broke through the soft-cap. Huge gamble not worth basing the whole decision on, though.
