If there is a complete control of the party like suggested, the devs *will* start to balance the game around this. It just happens naturally.
I also do like to issue commands and to position my squad tactically, it's just that since ME1 there seems to have been a constant devaluation, degradation and marginalization of the importance of such a management. Partly due to poorer AI, partly to ME3 being fairly easy.

Which begs the question why the AI gets degraded as the trilogy progresses. I prefer to believe the reason for this can be summed up to a senior EA exec complaining that EA games are too hard to learn. Therefore, ensuring console button smashing orgasmic pleasures.
The way things stand, jumping from one char to another does not add any advantage. The mechanic is to :
1. Only the controlled char gets the 2-3x advantage.
or
2. Only the PC has the power advantage,
Either way, I see no problems with this and there is no need to "re-balance" play. Also, for those that assume your incapacitation automatically makes you jump to another player, the devs can simply implement the "ghost" feauture whereby you continue looking at the battlefield via the eyes of one of your team mates (as in ME3 MP co-op play) until someone heals you or you lose the combat and must re-start.
Really, some people get uptight for silly reasons.
