I think the new gunner reload skill means we only have to click the mob once, and we will continue on firing our bullets (usually one click per fire).It'll make Gun Overdrive so powerful, we would not use Power Shot anymore. And the turret skill looks like it'll place a turret that autofires randomly on the map. I just hope we can spam it like Explosive Experts. though it raises questions like does the turret has HP and how does it damage output is calculated.
Another question is that, is this all of the new skill, or is it just the first wave of new skill added.
