Well then I won't lie that I'm a little surprised but so far people seem to unanimously agree than 2 and 3 are the best choices.

So with that said, few thoughts on regeneration

Caldari & Minmatar:

Caldari obviously need the most shields out of all of them, but should they get Recharge Speed to get that massive HP back faster? Or Decreased Delay so they're almost always recharging? I'd probably say go with the latter but the Delay bonus also makes a lot of sense for the Minmatar

Should the Caldari get Recharge Delay bonuses? or should the Minmatar? Thoughts?

Gallente:
Bonus to armor repair is obvious, that's how they work in EVE.

Amarr:
The Amarr are kinda tricky, as they're supposed to be the armor brick tanks, without much focus on regeneration. I don't think they should mirror the armor repair like the Gallente do. So while it's not really regeneration, how do you feel about a reduction to the speed penalty of armor plates? I feel it remains true to the Amarr racial theme as well as the idea of a skirmisher role.

I would prefer bonuses to be generalized.
Characteristics of suits and guns of the same racial alignment should mesh well, but both should also work on their own.
So a Gallente assault weapon bonus should apply even to Caldari, Amarr and Minmatar weapons. It would modify those guns in a way that fits the racial characteristics of the Gallente.
Alternatively, you can just drop the weapon bonuses and focus on the role by giving Assaults playstyle bonuses, like racial tanking. This way, all the Assaults will exemplify the playstyle that their races are known for, instead of being showcases of their guns.
IMO, no role bonus should ever enforce any kind of equipment. (There are some unfortunate exceptions, like cloaking, as the game's system isn't perfect, though)

We are mercenaries. A mercenary shouldn't care about the manufacturer of a gun. A mercenary should use what's best for the situation.
The equipment selection isn't big enough to allow a character (Or, hell, a squad) to be outfitted with a full racial setup, especially as there's a lack of intra-faction synergy. (Like Minmatar having the repair Logi, despite Amarr being the brick tankers who naturally require repair support)
That's why any combination of tools should work without penalties. Lack of synergy should be implicit (e.g. fitting a Nova Knife on a Sentinel), instead of being enforced by bonuses. A Gallente should want a Gallente gun because it meshes well with the Gallente playstyle, not because it's the only gun that profits from the racial bonus.

Other than that, I love the idea of putting one bonus on the medium suit.
