Well, we wouldn't do it if it blocked you from doing other actions. It will start reloading after you shoot, then if you do something else you'll cancel the reload and have to manually reinitiate it. Well, as I mentioned the LP cost will be lower on the basic Ork shield compared to the basic GA shield, which would mean you could spend more points on your weapon or survivability. Plus the Slugga can capture points. Yeah, the main problem I think is that he frequently holds it out with one hand, quite awkwardly. Ork polish is a big focus for the animators.
