Wait, you are saying that Minmatar aren't glass cannons as they are supposed to be, and thus you want to give them more tanking?

Minmatar should have high shield regeneration, but also a high delay.
Why? Because it encourages hit and run. Low delay is better for prolonged combat, as Caldari are supposed to do.
Minmatar shield regen delay and regen speed, as well as armor regen, should be synched in order to allow them to have both values topped up at around the same time after an engagement. This means that avoiding engagements after a fight is the way to go, because otherwise the shield regen timer is reset and you are at only half HP.
Their speed is there to allow them to actually make use of that healing. Run away and live to see another kill. Meanwhile, do something with lower risk, like running cloaked to the next objective.

Armor plates slow them down, meaning that this concept is interfered with. Shield extenders/regulators, meanwhile, would be the to go thing for them. This leaves open low slots for profile dampeners, which I imagine to be very useful for a hit and run kind of playstyle and movement modules, but makes tanking a tradeoff with damage modules.
I don't know much about the shield modules, but are the extender/regulators based on percentages? The shield delay modification might actually be something to consider with this version of Minmatar, in contrast to what I heard about the laughably low attribute change for Caldari.

Anyway, take my suggestions together and Minmatar would be the perfect lone wolfs. Run around the battlefield, assault undefended objectives or defend hacked objectives. The long time between attacks would be enough to heal up, but would cause death in larger battles. Mediums would be heavy on flanking and dynamically reinforcing the team even across larger areas. I don't have enough imagination for heavies.
Now, how fluffy is that kind of playstyle? Does "lone wolf" fit the Minmatar mentality?

they currently need more speed on the scout suit, as it is worse in every way than the gallant scout

Is it?
I thought the base speed was higher.

The current issue is that the engine simply can't handle proper sprint speeds. I also wish that Minmatar would be far faster.

+1 for good points but

No armor repair for you, get over it. the scout only has 70 armor anyways, why the hell would you even want that.

I think CCP will be changing the shield recharge and delay in 1.8 for medium minmatar. I looked over the other suit stats they released and minmatar will have shield regen abilities slightly lower than caldari but higher than the other two races. Currently they are the lowest. This is speculation but they did say they were making changes to dropsuit stats. Seems most lijely to me. I think this buff will go a long way. The buffs you mention might be a little op. Especially with the removal of caldari shield extender bonus and an increase in ttk.

Yes I do and always have played min assault.

Looking at the proposed new suits in the feedback forum, I predict that the Caldari and Minmatar assault slot layouts will be swapped after 1.8. Caldari will be changing to mirror opposite the gallente slot layout, and Minmatar will have a near balanced slot layout.

Meaning: Where as the Caldari Assault was the most versatile due to layout and dual tanking, the Minmatar will take over this role post 1.8. (PREDICTION*)
