Came back after a long time..

What the heck, a Heroes class just popped up in Reboot... Reboot used to be awesome for farming mobs together by overlapping zombies without losing HP to get Mad Buyers, but... why did they change it so that overlapping makes you lose HP? I played Reboot for the fun of not dying even when overlapped... So now when I play Original after playing Reboot, I just die in a bunch with my allies. I'm naturally inclined to just charge in.
