If you have the high-end stuff from STFs (MACO or Omega Mk XII), it's just about possible to do (others have done PvE with Mirandas, etc). It's insanely difficult, of course, due to the limited weapons, bridge officer seating, etc.
(For what it's worth, I used an NX in a Borg Red Alert with Assm. Borg Set, two dual heavy polaron cannons and chroniton torpedoes, and it actually didn't do too badly.)
there is not much possibility anyway...a photon or quantum torp launcher with spread and a DC or DHC with a turret in the back.
grapler is a cool console, keep it. If you have some other universal consoles, or the plasma defense turret put them on.
boff powers: torp spread, eptS, HE is a solid build to level
Can anyone suggest if its possible for the NX-01 to be a viable ship on
a. normal difficulty
b. one difficulty rank higher
And if so, what equipment is needed.
I am referring to PVE and i do not intend to do PVP.
I'm feeling a bit enterprise-ish and want to try using the ship, as my default ship, if its viable, when i replay.
I perfectly understand where you're coming from. Until level 40, I flew an NX-class starship on my Romulan character, complete with Polarize Hull and Dual beam banks for the authentic touch (of course, I had shields though )
PvP with this ship? Highly advised against!
PvE with this ship: The only PvE use for this ship that I advise, is for Azure Nebula Run. See the link in my forum signature for how to play that mission. I've run it with an NX-class ship, it performs well as long as you don't get fired on.
