Main support suits: Logistics gk.0 and Logistics ck.0
HP shouldn't be a concern, as although survivability is important, their capacity for out-tanking Assault was a primary cause for Slayer-Logi being a thing.

Nanite Injector: It's a ******* piece of ****. It's been 2 years. The guys on the CPM0 were telling CCP even before it was released how aboslute game-breaking terrible it would be if you can just pick up anyone. ATM terribads and troll are the only ones that carry them. More than any thing else there needs to be a way to avoid some prick with a dirty needle.
Secondly, the nanite injector is just terrible in that it only provides armor HP. It needs to provide Shield HP as well.

Active Scanner:
Needs to be re-balanced to detect medium frames. Best solution to that is to take away Gallente Logistics Scan Precision bonus and replace it with increased scan angle.
The recharge/duration needs to be closer. Not so you can constantly spam it.
So long as Gal-Logi has a bonus to precision Medium Frames cannot participate in stealth. 1.4-1.7 had many Assaults or Logistics running 2 dampeners. It was a much healthier game in that tacnet exchange.

Removal of squad-shared passive scanning will also significantly improve the desireablity of Active Scanner

Skill Bonus. It's been 9 months of me saying this: They need to be comprehensive.
The Logistics suits need to be the best at using all equipment. Not just a single one.
Fire the idiot, even if it was LogiBro, that thought it was a good idea or even acceptable to have these split up.
It's not even complicated.
