As this is an FFG thread, its worth explaining that FFG L5R weakens the role protection/delineation between the traditional Bushi (warrior) / Shugenja (priest/mage) / Courtier / Monk / (Ninja, shh) schools considerably.
In prior editions, you picked a school, it fit into one of those categories, and you got a technique each rank from that school (or one technique + access to a new spell level each rank for Shugenja). So, absent (supposedly very rare) multi-schooling, Bushi would only get more combat techniques as they went on, and Courtiers only more courtier stuff. This meant that by higher ranks the niche protection was extreme: bushi could one-shot Oni and courtiers had abilities approaching mind control.
In FFG, the technique divisions exist not in Clan schools but in categories: Kata (fighty stuff), Kiho (monk chi techniques), Invocations (spells), Shuji (social, meditative and leadership techs), and Ninjutsu (dishonorable stealth-based techs that no one admits exist). There's also a general 'Rituals' category that includes stuff that is basically universal Rokugani practice (like the Tea Ceremony). Individual Clan schools have access to 3 of these, usually 2 'specialized' ones + Rituals. And MOST Bushi and Courtier schools have access to both Kata and Shuji. The differentiation comes in a rank 1 school specific advantage, and school 'curriculum' that reward you for advancing in a semi-defined path and provide early access to specific techniques or possibly even toss in something special 'out of class' (IE the Hiruma Scout has the usual Bushi selection of Kata, Shuji and Rituals, but can access a couple specific Ninjutsu techs for sneaking around).
On the whole, everything is much more mix-and-match, pick-and-choose. And with only Rings rather than stats, there's not much of the potential min-maxing statwise that would generate socially inept Bushi in earlier editions. Being high Earth means you are enduring; that can mean shouldering blows on the battlefield, but it can also mean standing firm in court. So basically, it's much truer to L5R fiction in that the average Bushi will be socially competent if they put even the tiniest effort into it.
But yeah, it also expects that you roll social stuff, in part because everyone CAN participate. If you're not comfortable with social dice, it's not a good choice of system whatsoever.
