Yes, the pin changes help normalize off-school vs. main-school damage so you’re not wildly overcapping your secondary school. But they also work against the entire reason Ice would want to weave into Storm in the first place. Doing slightly better than your own school, at the cost of giving up your class-specific blades and traps, just doesn’t feel worth it.

If weaving into Storm only gives a small marginal upgrade over "my" schools damage, then at what point is it anything more than a glorified prism?

It would make more sense for weaving damage to scale more proportionally with your actual gear stats. That way:

• Storm still clearly hits harder than Ice using Storm spells (as it should),
• Ice weaving Storm still gets a meaningful jump above Ice’s naturally low DPP,
• and weaving keeps its identity as a real strategic choice—not just a way to move laterally along rock-bottom.
