To me it looks like they are creating utility by fusing certain abilities together. Here’s how I interpreted what I saw in the benchmark:

WHM: Divine Bennie + Protect
SCH: Adlo + Haste
AST: Barrier that procs a heal

In previous benchmark trailers they didn’t always showcase the most interesting new skills, so I’m cautiously optimistic that they are saving the good stuff for the Actions Preview, but we will see…
