Why would that be important? Everybody cooperates at endgame anyway... for fighting the Borg, the Undine, the Iconians, Rebel Klingons, Tal Shiar, or any of the other endgame opponents. So why not have Cardassians in Task Force Omega and elsewhere.
Agreed. Apart from story reasons, seriously: A Borg player ship in an STF?
Simple. You replace the AI for the Borg. With your ship of course.... Hehehe..... KDF and Feds can has DAI NAO! mwhahaha!!!!!
Ok I agree KDF need a finish but that's a long shot for the Devs.
Because KDF you can write a bunch off internal afairs story's KDF also need a diplomat side.
Not a pirate one or get rid off Jm'Pok in a good story line, and set a new leader one who wage peace again with the Feds. NON AGRESION pact with them.
after that build up the empire like the Gorn Ambasador said in the mission off the Borg Convension.
Let them be allies with the folowing species :
and the rest they are allied with
Let the KDF do trade buisness with :
Romulans have there new world and they could have dealings with the minor species in there teritory's like :
When making the Cardessians a playable race let them be allied with :
Let them have trade deals with :
But let's have an story line about finding out the hideout off the cardesian rebel faction
They start a war with the romulans and remans but also they would start agression against some other species and let them have deals with the gama quadrant species.
Also it would be an nice race to have because they have nice ships and break there treaty with the Feds and start there rebuilding of there fleets I think you can have a nice story to tell for exsample how they diverted an direct atack from the Borg, where the Feds realize they need the cardessians as allies and need there fleets against the Borg.
Just what I said there are good story's to tell about the Cardessians.
If there's ever going to be an fourth playable species I would vote for the Cardessians.
