dwan trail rpr: Reducing casting soulsow time to 1 GCD and gain 10 more soul?

After proging / farming the new savage by playing rpr, I figured out that casting harpe is some how anoyying. If we can make harvest moon to cast more than 1 time during a game to deal with chariot by utilizing some spare time like pict's drawing, rpr will be much funnier.

I think harvest moon is one of the most iconic skills of rpr, casting only one or two times in a combat is not enough, if reducing the casting time during combat of soulsow and gain 10 more soul (as casting harvest moon + casting soulsow is 2 GCDs in total in the case so if harvest moon should gain 20 soul in total to avoid total resource loss),I believe more rpr players would chose to cast soulsow during combat to deal with some hard mechanics using harvest moon rather than forced to use ingress or egress to get a immediate cast of harpe.

How do you think if this will actually implemented?
