Ship: Guardian Cruiser
Visuals:
If the Galaxy class and the Ambassador had a baby, it would be the beautiful Guardian. At least I love the classic looks of the thing. All textures look smooth and the weapon firing arcs are all smooth with no cut through on any part of the ship. Your beams fire off from the saucer arrays, 2 ventral arrays, and arrays top and bottom of each nacelle. You also get 2 different hull options along with a type 7 skin option. The other hull provides mainly the option of different nacelles, a smoother neck, removal of the "baby" nacelles, and the option for a swept back style pylon section. If you are like me and love the more traditional look of Star Trek ships, you won't be disappointed in having to look at it while you play.
Pros:
This thing is a tank, with me being a Tactical, while also putting out really good damage. I also find it to be one of the most well rounded ships I've ever used. Having the options with the Lt Engineer/Intel slot and a LCDR Science station opens up things. With my build, my shields almost never come down. Most the hull damage that I receive is bleed through and even then my hull has never dropped below 90% even in advanced queues. I've also been putting points into the Pilot skill. With my Attack Patterns, it grants me additional hull points which absorb most of the hits to my hull that I do receive. The mastery trait I'm sure is worth it, but with my build and the Pilot benefits, it's never been stand out. So I can't say how affective it is. The console though is amazing. When things get hairy in a pile of enemies, just pop it with a beam fire at will and things begin to melt while you continue to absorb almost all damage (75% incoming damage absorbed and put straight to your own weapons). It last 20 seconds and with the new 2 minute cooldown, in my opinion, this is the best Zen-Store console out there. But it's only for the Guardian. They should of named this thing a battleship instead of a cruiser.
Cons:
It being a big ship like the Galaxy, it comes with the slower turn rate. So it's not going to be as nimble as the other cruisers. Though with the Omega Pattern, my boost to turn on Neutronium consoles, and a decent skill tree counters it to provide a decent turn rate making you feel like you're in a powerful battleship and not a slow moving whale. The 3 Tac slots also don't carry quite the punch as the 4 slot cruisers. However the ability to absorb stuff out weighs that in my opinion, as it can absorb more then the other cruisers. I didn't notice a huge difference from the assault cruiser, but it's still noticed, and it might be due to the special console. But some of the Vaadwur battles left me missing my face-melting cannons and my 4 slot Sovereign.
Conclusion:
I've bought a lot of ships I've regretted getting and wishing I could have the money back. But the Guardian, like my Akira, I would buy again. I've really enjoyed this ship. If any one is wanting a good tanky battleship that does decent damage but takes tons of hits, it's worth the T6 upgrade. If you already have a T5-U Fleet Assault cruiser or similar, the only thing you will really gain is the console and LCDR Sci bump. While great, it's something to consider and possibly sticking with what you have and doing the upgrade.
