I'll admit, Scarecrow wasn't a character that I had any interest in before... but after seeing his moves in action, I'll probably have to add him onto my ever-growing list of 'new characters to try out' with a view to using him as a main or secondary.
I actually see a lot of parallels between him and INJ1 Raven. They both have a projectile absorber, Scarecrow's teleport looks like it has comparable frame data to Raven's, his crow gear move is ultra similar to Raven's df1, and it seems likely that he'll excel at similar ranges to where Raven did as well. He also seems to have elements of D'Vorah (Venomous especially) too, so that's pretty awesome.
Narrowing down to a main is going to be a long, slow journey at this rate...
