Not sure reactions are correctly described,
"Reactions are a way to give positive feedback to other members. A way to say “Thanks” or “Nice one”. '
The two middle, of six reactions are not particularly positive.

Or am I missing something?
Kudos were unambiguous and were a sign of unqualified support for a post on the old platform and were a factor for calculating payback.
As far as we can see, Reactions are not in the same league, as they are qualified and are open to interpretation. They are not necessarily supportive of a post but a reaction to it.
