The challenge faced by our Wormhole group has been to develop a doctrine from the new T3 Cruisers that had the right balance of DPS, survivability and utility but at an affordable ISK investment so everyone can get involved. As wormholers, Covert Ops ships are always important, the fact that using a Covert Ops Tech III Cruiser means you no longer have to get by with meager DPS is a delightful bonus. For OpSec reasons I'm not going to share the specific fits of our fleet doctrine, but let's just say it's rich with Tengus.
Covert Ops Fleet Composition.
DPS: HAM Tengu, buffer shield tank, 900+ DPS heated.
ECM: ECM Tengu. buffer shield tank, 600+ DPS, 3 x Multi spec ECM
LINKS: Boosting Tengu, buffer shield tank, shield/skirmish links, 4 x dead space medium remote shield transporters.
Now here's where it gets tricky for the enemy. They all look virtually identical. I pity the FC who has to call primaries when he has no clue which Tengu is doing the most damage, providing the logistics or engaging in eWar. It's no longer a matter of just saying "Primary the Falcon/Jamgu" as, unless the FC is being directly jammed by the offending ship, he will have no clue which is which.
The doctrine is still being developed so I'm sure there will be changes made as limitations are discovered, but if you see a swarm of Tengus uncloak in a wormhole near you I advise you to run, Forest, run.
