Warning long post
Since there's no reaper, spectre or Outrider I decided to come up with these.
Hawk: Hawk is a specialist with exo suit that can let him (only him) to boost jump to get to certain areas.
Equipment: throwing knife
Rogue: she's a specialist with the Sparrow
Equipment: Smoke green that gives her thermal vision countered by Ghost or whatever perk it's called
Knox: Knox has the railgun (basically whatever the ***** reapers arm thing is called)
Equipment: proxmity alarm: makes a noise when enemies go by it giving away their position
Rain: she has tear gas which makes enemies vison go blue and has tear effects causing them to lose vision slightly and choke and cough
Equipment: C4, Obviously you know what it's for but can be used blowing up equipment and the enemies.
Mirage: he's a specialist that has 2 holograms of himself that can walk, crough and copy real player movement to fool enemies.
Juggernaut: he is a specialist that can self revive himself when he's down and his teammates
Equipment: bouncing betty
Shel: she's a specialist who has a special gun that sprays out bullets that bounce off the walls and hits targets near by
Equipment: Jammer: she can jam equipment with it.
Take the specialist out of the game period. Give gamers the attachments that we should already have in a Black Ops game and give me a real ranking system.
