For better scouting ideas and roles, how we fight, and to learn about how scouting exists in dust I recommend you read up here.

Sit down and get comfortable. It's quite the read.

Then play a scout with the intent of the "roles" you outlined here. You can pretty much accomplish it already with the two racial scouts. Then come back and you'll see why none of this works out too well.

I'll admit I stopped reading after your Minmatar Scout suggestion. It became clear it was a waste of time.

Thanks for trying, though.

Since CCP is going to give the Scout suits a look over, I figure I'd toss up my ideas. I think there's a way for each suit to relay some sort of useful/helpful info that justifies it's "Scout" label. We need to give each scout a role that will make them not only desirable but in some cases needed for victory.

-Minmatar Scout-
Role: Assassin

When it comes to it's role and bonus, there's isn't anything that needs to be changed. So why am I bringing it up? Because I think it can be used more tactically(if that's the right word to use) by adding one thing, a kill beacon. The suit should broadcast every kill to it's allies through the Tac-net. A small, downward pointing dagger icon will flash above every killed enemy for a couple seconds (doesn't matter what weapon is used to kill, same icon will appear.). What that dagger tells you depends on when you see it and where. It could tell you a pesky sniper's been taken care of, or that nobody is manning that hostile turret anymore, or just let you know you got someone behind the lines making a nuisance of himself and distracting enemies. Put teamwork into it and that beacon can tell you a lot more.

-Gallente Scout-
Role: Locator

This suit should be a walking active scanner, every enemy it senses should be seen by allies. That would better compliment it's skill bonus. If it already does that then cool, no changes needed.

-Caldari Scout-
Role: Identifier

What could make this scout useful is the ability to tell you what you're facing. This scout could ID enemy suit/vehicle types, it's label appearing over the enemy, just above the "enemy unit" icon. For standard frames, the label "Light", "Medium", or "Heavy" will appear. For specialized suits, it'll show "Assault", "Commando", "Logistics", ect (same logic for vehicles). Depending on your Caldari Scout skill, you can ID more than one suit to a max of 5; The 5 closest to the center of your hud or weapon cross hairs. This would make the Caldari scout a sniper's choice because it would help the user pick off high value targets. This bonus could also couple well with active scanners and Gallente scout suits. Allies will be able to see suit labels on enemies that are being both scanned and ID'd.

-Amarr- Scout-
Role: Infiltrator

Drop Uplink spamming is becoming troublesome. What could help is making it more taxing on a suit's CPU and Grid to fit one. That would give this suit a very desirable role indeed. Should CCP tweak the uplinks, the Amarr scout suit could receive a bonus that reduces CPU and Grid usage, making it cost less for every skill level. It's role would be to make little base camps behind enemy lines. Like the minmatar suit, it will have a tac-net beacon. This one broadcasts a drop uplink icon over the user when an uplink is set.
