Ya know, I've kinda been trying to steer clear of anything related in comparison to "multicrew" because it really doesn't have any benefit to Solo as it's currently implemented.
It *would* be nice to have something that Solo CMDR's can benefit from, and NPC hirelings could be a way to assist with this. Not entirely sure a "pip" is the answer, but definitely some passive bonuses of some sort if they're not going to actively man/woman a gun or station somewhere.
All 3 modes being "equal", of course- you know... PvPer's being "neglected" and all that. (ahem, multicrew)
In all honesty, player crew only grants you three advantages;
1) extra Pip.
2) chaff-ignoring turrets
3) potentially second fighter (skill notwithstanding) but be unable to launch yourself in the fighter
The deviant difference currently with NPC crew is that you get to;
1) launch one fighter, or fly the fighter
*) also costs extra credits, you loose out on income from Bounties and Bonds
That's pretty much it. Personally, I'd be all for the whole list - crewed ship turrets would ignore chaff, or you get to launch up to two fighters and that additional pip per extra crew.
Of all the list, the Pip is the most important when you calculate shield strengths. Increasing Sys Pips grants stronger shields, on Eng and Wep is increases power recharge. having additional pips would drastically improve ships' performance portfolio.
The risk is in the wing differences currently. The intended difference I see was to have it so a single crewed ship could match a wing of ships easier. Probably more to do with instancing and coding restrictions, but that's a balance too.
I can see the never-miss turrets being an issue, and the extra fighter could be trivial in all honesty - its the Pips that really change the game.
To me, as it stands now it would be essentially a non-issue of balance because everybody would have access to the same effects, but I can understand the reservations on some of it for balance and all that.
I would still want it.
