The Injector is THE piece of logistics equipment, correct? When you think of a healer in an FPS, it's usually the reviver, whether he has defibrillator paddle, a medkit, or a syringe. So why not just fuse the Injector into the Logistics Suit, like the Knife used to be a part of the melee system? It would make the need for a Logi easily apparent, as they would be the only unit capable of revives, and would work well with already established plans to alter the skill bonuses. Each Logi would have differing revive stats as well, if it fits your fancy. Otherwise just ignore this next bit, I just wanted to get yelled at today...

Caldari: Revives at 80% Shield, 20% Armor. This exemplifies the Caldari Shield focus, allowing Caldari Dropsuits to be brought back at a decent health value.
Minmatar: Revives at 60% Shield, 40% Armor. Minmatar Dual Tank, but tent to rely on speed as well. This will allow Minmatars to be brought back with a decent buffer, as most have poor armor, but all have a small built in repper.
Amarr: Revives at 60% Shield, 60% Armor. As the slowest and tankiest, but undecided on what tank they use, Amarr get the largest base heal at 120% total. This is to offset the Logi's far slower speed compared to most Logis, and it also paints itself as the starter Logi for Assaults wanting to branch out, what with it's even revive stats and sidearm.
Gallente: Revives at 10% Shield, 100% Armor. As the creators of the tech and the highest Armor Focused race, Gallente get a base heal of 110% and a full-out Armor revitalization. They are also planned to get nanite Injector bonuses, so maybe they can change it to Active Scanners?

NOTE: I pulled these numbers out of my arse. Please feel free to debate what they should be, but try to make a post on the general subject. Whenever someone states numbers, real conversation and dialogue tends to get buried under the precise number debate, so please do not lose yourselves.
