I use this all the time, for instance, you can place your ranged out and use a rogue as bait. Once he gets aggro he can cover the most ground/turn to lead the group into an ambush.
You shouldn't have problems doing that with the whole party in the turn-based mode, If I understood right what you're doing. Your
ranger is standing doing nothing isn't he? So he's not utilising his ability to act in real time. And your
rogue chased by enemies runs to the ranger, isn't he? So he's not in real-time at all.
I'm talking about quite the opposite situations here, try to read more carefully, please (not intended as offence).
