Currently watching gameplay vid for Gears Tactics. Curiously they have dash just like OP suggested (8:15)
That said, GT doesn’t use grid, which allows for smooth 360 movememnts… which with balistic simulation might have been a good fit for PP, though generating maps in that manner would be a different kind of challenge I imagine.
EDIT. Also they take on skill tree seems interesting - at least theoretically. One can choose from whatever tree they want, but with limited total skills they can learn, they won’t be able to combine multiple high level skills. Those are still within single class though, but the underlying design sounds solid to me - specialization and dipping into multiple trees have obvious advantages and clear tradeoffs.
