I'm making this post mainly bc Hakaishin posted his Dreadnought and it made me want to share.
Fore weapons - [Retrofit Forward Phaser Bank Mk XI [CrtH] [Dmg]] and [Photon Torpedo Launcher Mk XI [CrtD] [Dmg]x2]
Deflector - M.A.C.O. Graviton Deflector Array Mk X

Shields - M.A.C.O. Resilient Shield Array Mk X
Aft Weapons - [Retrofit Aft Phaser Bank Mk XI [CrtH] [Dmg]]
Devices - Red Matter Capacitor and Subspace Field Modulator
Engineering Consoles - Field Generator Mk XI and Shield Emitter Amplifier Mk X
Science Consoles - Enhanced Plasma Manifold
Tactical Consoles - Assimilated Module
Boff powers(If you get aby BOFF with Efficient it helps A LOT)

M.A.C.O. gear will be updated to MK XI when i get the chips.
This set up lets you deal with most of stuff in game, you can even do STF's on normal as well. Just keep in mind your not going to be great anything and if your ships drop odds are you are dead really fast.
My skill build is based off Hakaishin's Dreadnought build
