No, we've come full circle on that.
Freeze was originally 100% reduced action speed (back in the day there were no more/less modifiers. It was a simpler time). And that was fine, because that would always fully stop things.
Then at some point we added something that could increase action speed, and it was no longer fine, because that let things move while frozen, which was unintended. So freeze changed to a magnitude of something like 200% reduced action speed, which solved the problem temporarily, but was never going to work long term.
Eventually as action speed modifiers became more complicated, freeze was changed to have a boolean effect which set action speed to 0, ignoring (most) other modifiers. As a boolean thing, this couldn't be scaled, which was fine, because freeze wasn't a thing that could be scaled anyway.
Some bosses got various forms of "action speed cannot be modified below X", shown as "cannot be fully slowed", which freeze did respe...
