If you let me play devils advocate there, 15% APR on HBD is great, but only in bear markets (Vs HIVE). It seems that markets will heat up soon, and a small increase in HIVE price terms it's enough to justify the apr reduction.
In that sense PWR it's like a HIVE derivative, but with a much higher apr and the possibility to stay "liquid" in the pool.
Regarding leo... nothing to add. I feel more or less the same.
Have a great day.
