I think so, yes... but sometimes its worth it
Edit: About real time:
Do you ever split up? So far I only sent in 1 squad of 6 (3 toxiguns, 3 devestators) so that my soldiers spawned together and then split them into 2 squads (1 per weapon type) and found a nice place to fortify my position. I'm wondering if there is another way, something more effective and safe. Turn based seems to be a lot safer in some respects, if it wasn't for those disruptor shield I captured thanks to the toxigun I'd have a lot of casualties during every mission.
