I like the option in the Lobi Store that allows you to upgrade the Mk XI Jem'Hadar space and ground gear to Mk XII gear with better specs.
Can the devs please offer a similar "upgrade option" for the Breen space set?
The set bonuses from the Breen set are pretty nice but the specs for the individual deflector, impulse engine and shield simply aren't very good compared to the various Mk XII gear that is currently available.
I'd be happy to spend 200 Lobi to upgrade the Breen set to Mk XII if that was an option.
In the immortal words of Captain Sisko: "It may not be what you believe, but that doesn't make it wrong."
The Jem Hadar set upgrade came along with the Dominion Lock box; so if its ever added, its most likely to be added with a Breen Lock Box. Unless they've made plans to definitely NOT make a Breen Lock box, I wouldn't hold your breath on it being added before then.
