It seems like your Sentinel resists might make more sense if adjusted somewhat.

Check it:
Caldari: Shield resists against the two weapons that have shield bonuses
(they're the shield tankers, makes sense)
Gallente: Armor bonuses against the two weapons that have armor bonuses
(they're armor tankers, makes sense)

In both cases, the resist for their racial enemy is higher than the resist for their ally, which also makes sense.

On the other hand:
Minmatar: Shield resist against laser weapons, armor resist against blaster

You're dual-tanked the minmatar with a shield bonus against their racial enemy (makes sense) and an armor bonus against their ALLY that uses a weapon with NO armor bonus (makes no sense). It would make more sense for their shield bonus to be against their racial enemy (as-is), and the armor bonus to be against the other enemy (who's weapon is armor bonused).

Amarr: Armor resist against projectile weapons, and shield resist against rails weapons.

Same issue. You've dual-tanked the Amarr (fine) with armor resist against their racial enemy (makes sense), but Shield resist against their racial ALLY who uses an armor-bonused weapon.

Seems like a mistake, both are getting bonus against an ally's weapon on a resist that weapon has no advantage for. That's my first-glance reaction.

Commando skills is ****. Thanks for nerfing an underpowered suit even more...

So why does the Gallente Commando get natural ammo resupply but the others do not?

EDIT: That says armor, not ammo. My bad.

An observation:

The Amarr Commando's stats break a trend from the other suits. It has 650 ehp, which is the same as both the Gallente and Caldari.

So, the Amarr Commando has no hp advantage, the same number of slots, but is the slowest Commando. Is this intended?

Just to add, the Medium Frames are all getting some base stat adjustments, but no changes to slots (though that's not ruled out for post 1.8)

I would like to add that at this stage, we have not rebalanced the slots and PG/CPU for the medium frames yet, and it doesn't look like we'll be able to get it into 1.8. Expect those changes to come at a later date.
