Use Jamba add on.. which have an amazing feature : follow every x sec..
you can turn on and off the auto follow feature (by a macro command) .. and belive me your melee toon will never stop fighting or loose /follow

I don't need anymore to press 'space' and then my "/follow the leader" key while casting my 280 % mount .. I just press 'space' and then fly around whitout even thinking about my toons... they're always here after following me like a bee after a piece of sugar...
