there needs to be a unit that you can customize and make a marine with a diff wep or a beetle tank with a man out of it that you can control. They shouyld also make it so your alliance colour (whatever it is) and your starling have a small mark on there heads or something.
i wish you could give friends coins and minerals and there should be two types of rival battles the regular one and another were you fight the other teams units only in an arena or something
the one problem i when there is a group of five techs and shockers is almost inpenetrable with the turrets and healing guns even 2 blazers can bearly destroy them. maybe make a way to destroy that strategy?
