Though there are a few big differences, my 2000 pt army list is actually pretty similar to yours, Gr1m_dan
Since my army is so similar, I can't really provide much new insight, but I can vouch for the army's joy to play. I don't win every time but I'm never a pushover and it is a ton of fun.
I love my stealth team. They are the perfect "interference" unit as they can put out a large amount of pulse shots while being really hard to remove completely. I run mine with the CDS and gun drones. I tried marker drones but I wasn't impressed, that's just a preference thing though. Nevar
, my seekers usually surprise me with their accuracy. I always expect more misses than I get. Longstrike, however, is another story entirely...I am pretty sure his hit rate so far is 50%...
I have been toying with the idea of converting myself a Shadowsun. I rolled her warlord trait on my regular commander for the first time a few weeks ago and I LOVED it. Shadowsun could be the extra bit of anti-tank that I need. My list is lacking in that department, and I need to adapt to my new LGG since more than a few players use Land Raiders and now there are Knights.
I just need to ween myself off of the plasma...
