No. The Enclave are dead. They were the villains in FO2 and in FO3. They were destroyed in both games, so I find it very unlikely that are in the game at any capacity besides remnants like they were in NV. There gets to a point where we need new enemies, new stories, etc. Now, I love the Enclave and I will do everything in my power to get the Enclave PA, when I finally get FO4, but we need to move on... Side note: In my opinion, the Enclave PA looks way more bada$$ then the Brotherhood. I'll be mowing down the BOS in the sick Enclave PA...

I think the brotherhood (and i mean EVERY branch of them) should be destroyed (something about them pisses me off for some reason.)

I agree they should include every Fall Out design possible and would hope they include the MW BoS advanced armor from Tactics, http://fallout.wikia.com/wiki/Power_armor_%28Fallout_Tactics%29 that the Enclave advanced armor is supposed to be based on, such armor is not as tank like as the T-60 and should be wearable in buildings.

Personally I was never into the insectoid looking Enclave armor , I expect there are those who will find armors I find practical or impractical, just the opposite, they are playing their game, I mine, let us gamers have as wide a selection as the franchise has offered, it is not unreasonable the expect The Institute to have acquired as many samples and variants as possible. Traders who have acquired tech The Institute might be interested in, to try and sell it to a buyer like The Institute.
