Alright, so, I'm still deciding between Fleet Tactical Escort, and the (basic) Armitage, but I was wondering what the best Rep gear sets were for either/both of them.
Basically, both the Assimilated Deflector/Engines plus MACO shield has been suggested, as has the Adapted MACO set.
I've gathered up about 3000 marks, so I could get either. I'd probably only get the Mark XI Assimilated pieces, since that would save me a huge chunk of dilithium and the stat difference is within a couple points/percent of the Mark XII.
I only run one torpedo in my build right now, if that helps, since the torpedo damage bonus is probably a big determinator.
Personally, I'd pick two pieces adapted MACO (with either an elite fleet or normal MACO shield) over 2 pieces borg. Just love the bonus torp damage, and the boost to aux can help heal powers a bit as well.
Truthfully though, in an escort I'd run the Omega engines and deflector, with either a MACO or Elite fleet shield. Tet gilder is incredible for stripping shields, especially if you have 6 ranks in flow caps (and/or a romulan flow caps console).
In addition, the omega engine is arguably the best in the game for turn rate and speed, while the deflector gives a bonus to targeting sytems (this helps make weapons without acc mods, eg cutting beam, more viable).
I use the full MACO set on my escort and my Bird of Prey. The deflector adds shield and hull boosts and some sci resists, and of course the shield is the best for tanking. The engine isnt very useful but the 3-piece bonus can be useful as an opening move to temporarily disable your opponent.
I'm in the same spot with one of my characters. I've got T5 Omega rep, over 3k marks, and all the ECs and Dil needed to grab a set of Mk XII gear. But I've just been sitting on it, trying to decide. The Aegis set got me to this point, so it's not like I feel I'm suffering. I just don't know really what the best option is for a Charal (the Engi slanted Kumari). And don't want to waste marks till I make a decision.
I also don't have access to my fleet's provisions. It's kind of weird. I did the other day. But settings got changed. So I don't know what's going on there.
