Yi Sang’s Blade Lineage ID has the potential to be a really good DPS because it fixes the biggest issue of Poise status - it disappearing at the end of the turn. Yi Sang makes it appear next turn and on top of that, he gets to keep it with his passive that lets it stay turn longer.
However, keep in mind that Poise is an unreliable source of additional damage so there is simply no way of setting it up for your best nuke skill. To make things worse, the numbers on his skills are not high enough to make him a good clasher and other Identities simply out-damage him thanks to their skills being more reliable.
fixes the issue of the Poise status,
when RNG favors you, his damage is simply great.
the issue is that RNG hates everyone and turns her back on you when you need it the most.
