So far… honestly, I don’t feel like it’s made much difference. I glanced through the name changes, and most of them are intuitive so I don’t even know that I need to bother “learning” the radicals again.
My kanji lessons have gone fine so far. Occasionally they use a new name, but it either makes sense already or I just incorporate the new info as I go.
Looking at the mnemonics for things I’ve got wrong, they’ve either been the same, the rewrite hasn’t been significant enough to make any difference, or it’s just given me a fresh perspective on something that was a leech anyway (so clearly I wasn’t remembering the previous mnemonic!).
So I think it’ll take a couple of weeks to get used to things fully and then it’ll probably just be better (because it does all seem more consistent). I’m concerned that there’s been an overall shift towards less ‘impact’ in the radical names, but the mnemonics so far have seemed good, and it’s probably balanced by many of the radicals being closer to their traditional meanings.
