I have just hit T5 Omega rep and the rest are not too far behind. I quickly bought the Assimilated Mk XII deflector and engine as I have always loved them. The extra strength, hull regen, heals, sector speed etc. are all great. For Fed/KDF, I have usually gone for the full 3 piece as I like the shield, despite the low capacity. It's the quick shield rebuilds, especially if the multi thing procs.
DL is a little short so I would like to buy one decent shield that will be a good 'jack of all trades'. It will be for my Corvette for now (I really like it) and also my Fleet T'varo. I may get a bigger ship later but assume it will be for escort sized ones.
PVE mainly but want to try to get into PVP.
I have it down to:
1) MACO Mk XII
2) Elite Fleet Shield Res B
3) Assimilated Shield Mk XII
Omega Mk XII was in the mix but I think I may as well take the Assimilated over the Omega.
I can't really work out which would be the best overall so seek opinions.
I'd ordinarily say go with MACO - great shield, but best against the Borg and not really terribly versatile if you're going to use it in Fleet Alert/Azure rescue etc etc, where you get different enemies with different weapon types.
I use the Adapted MACO on my primary ship mostly, although do tend to swap it out for an Elite shield when go into Fleet Alert etc, as the shield's ability to adapt to weapon-type can be of great benefit.
Elite shields excel in PVP where there's a huge volume of fire, but in PVE where most enemies do just a few large hits, the resistance buildup isn't going to be as significant. Plus reputation shields are a lot cheaper, and if you get the Adapted MACO or Assimilated shield, you get a heck of a bonus power besides.
I also fly a fleet T'varo and Corvette a lot, and a big problem I notice is the low hull actually makes weapons fire bleedthrough a big deal. I always run a Resilient shield on those ships since it helps big time. The Borg shield is Regenerative, which isn't that great.
You can't go wrong with a MACO XII (which is a resilient shield), or Elite Fleet Resilient Res B. I use a Borg Deflector/Engine for the hull heal proc and the Elite Fleet Resilent Res B on my T'Varo/Corvette.
IIRC, I would have to buy the whole MACO set to unlock the Adapted one? Too rich for me if that's the case.
As of yesterday, you don't.
As mentioned the stock Maco shield will conflict with plasmonic leech. Combine that with a somewhat smallish capacity (relative to other available covariant options), and it drops a few ranks in my book.
In the PvE realm I'd advise either an Adapted Maco or an Elite Fleet Covariant. On a T'varo the A.Maco will get you a capacity roundabout 10k or so, while only losing out a smidge on resists (with maxed shield power and an EPtS that 10% drops to about 6-7% or so due to the way shield resists work IIRC), not to mention the big killers in PvE are torpedoes that wouldn't be affected by that resist anyway.
For reference, my fleet Mogai sits at 12.5k shields without any console boosts from an A.Maco shield. With .11 less of a shield modifier you're going to be in sight of that number.
