Curation rewards in comment is gonna be ugly. It's evident to me that we should remove curation rewards from comments. I think 38% is way too much though, maybe 10% or something and also consider increasing curation reward percentage on the other 90% pool. Curation rewards are the main reason why people buy SP now, you should increase this not decrease it. If authors gets 10% less reward they will keep posting, if curators get 10% less curation rewards they will buy less SP.
