Anyone can be immediately useful in Dust 514, At the very worst a newbie can run counter sniper with a militia rifle and provide overwatch and recon support. Most snipers pop with a single headshot and most aren't moving.

Can or will there be an equivalent to Eve's tackle frigates (in immediate usefulness) in Dust514?

In Eve, brand new players can really ruin another player's day in a matter of a couple hours worth of skill training into tackling skills. In a week that can be a fairly useful disruption frigate. Tackling is a technique that occupies an enemy vessel not letting them escape. Sometimes when used against a much larger enemy the tackle frigate can fit its tank to be mostly invulnerable, but often they are vulnerable just enough to hold down an enemy long enough for friends to show up.

I'm thinking that a scout or logi hacker with either sprint/dampening mods and some remote explosives, could pose a pretty decent effective-new player addition in a lot of skirmish matches. It would go against a sort of FPS instinct of players wanting to grab a rifle and begin shooting people, but it would be sufficiently disruptive, split forces, and start teaching a player the usefulness of watching a map, using cover, and getting a feel for how battle lines move.

Don't kid yourself, that never happens

If the tackle worked on vehicles. oh wait there is one.

Webifier mine.

Well the difference is in DUST, any new player with a gun is a threat to a proto suit, so the role isnt as needed. I wish there was some equivilant for dealing with tanks though. A way to shut off the tanks engines so they cant flee...

What's a tickle frigate?

Oh yeah sure then i want a afterburner/micro warpdrive on my tank and equipable wings so i can fly around the map.
