Operative: The ability to use the basic Abilities of the class they disguised as.
The ability to hack while in disguise

Soldier:The Ability to Plant some type of bomb or something to reduce an engineers progress

Medic: The ability to become Ivunerable for a couple seconds but can only use it on themselves and has slow recharge

Engineer: could not think of one and they already do half of the things in the game

These are a couple thinng I thought of

comment if you thin of more and hopefully it will be in a DLC after the one we are about to have

All of those sound great... You also hit the mark with the comment about the Engineers.

Yea thats basically what you have to have if you play with AI

I like the ideas, but just a few things to note:

The only engineer objective that doesn't take forever to complete is the crane repair on Container City. Imagine trying to do Shipyard with the Resistance being able to undo your repair progress....

The Medic's already have this ability, granted it doesn't work on themselves. SD did this for a reason: It doesn't promote teamwork. Why would a medic need to be invincible anyways? You can revive from 6m away and it only takes a second. Planting/repairing/hacking take much longer.

The engineers do seem like they do most of the work in the game, especially on defense. I would like to see other classes undoing objectives.

Being able to hack in disguise would be very interesting, but I don't think operatives should be able to do the stuff other classes do. At the very least, a crosshair while disguised would be nice.

yes, i think soldiers should be able to say... lower the progress on some construction objectives. (we carry around demolition charges. why not?)

I understand that the engineer objectivestake forever but the Hack objectives take just as long and then it gets taken all away in like 5 seconds when they sat there for a forever hoping they would not die and an engineer would be around

I do that all the time, it's called being an operative! (j/k ) I love the idea of operatives being able to stay disguised while hacking, but wouldn't that be very noticable anyway?

My Idea was to have the PDA in his pocket and the team would have too figure out wich person was the on the other team and they would not be able to just deactivate it. and If the soldier cant decrease Engineer progress(which I really Want) the operatives should not be able to get all there progress taken away by one little engineer in five sconds.
