So to sum up, if you don't care what race your warrior or shaman followers are in a melee group you might want to consider choosing tauren as the followers for this very reason! On another note you might NOT want to have a tauren as your main in a melee group, unless feral druid, if the rest are anything but tauren as that will only increase the /follow distance problem with melee groups!
and sorry, no wonder you didnt understand because u didnt post it >.< thought it was u hehe im sorry.

but tauren melee range is 9 yds and everyone else is 5, so if your main is a 5 yd hitter the taurens will be able to reach the target from the follow position.... im confusing i know lol. i confuse myself >.< hehe
