Pretty good to help with queue times and getting some exp/items for yourself. There are several limitations to consider:

1. The dungeon selection.
2. How much GC seals you are willing to invest.
3. How often you are willing to grind the Squadron Command missions to improve the stats of your squadron members (Offensive 5 is absolutely beast with the 60% attack power increase. All 8 of my active squardron members have it.)
