I'm not in alpha, but i have seen actual gameplay outside of those in the official videos, and even though the person used every ability often, it was never hard to tell what was going on, nor did it fill the screen with too big effects. Maybe it was because they had the camera further out, but the issues being complained about just were not a problem. Who knows if it will be the same or not. No point in worrying about it until we can actually see one way or another and SE is actually looking for our input.
